NSK TL bearings double service life in papermaking machinery
NSK spherical roller bearings with TL technology are being increasingly adopted in the papermaking industry as more machinery manufacturers and paper mills seek to maximise operating life and uptime. The unique attributes of NSK´s TL (tough and long life) specification is proven to provide greater resistance to hoop stress, subsequently reducing inner ring fractures and delivering service life more than twice that of conventional bearings with standard heat treatment. TL series spherical roller bearings are specifically designed for sections of papermaking machinery where elevated temperatures prevail, including dryer rolls, calender rolls, canvas rolls and PV rolls. The bearings were developed as a solution to a specific problem: inner ring fractures. This problem is common on dryer cylinders (including Yankee dryer rolls) and calender rolls, where steam is passed through the hollow axis of the roll to heat it. Here, the journal expands faster than the bearing, making the fit tighter. As the hoop stress (force exerted circumferentially) of the inner ring increases, cracks can begin to appear.
High temperatures in papermaking machinery also present further challenges to bearings. For instance, the presence of heat lowers the viscosity of lubricant, reducing bearing life, while unwanted creep can have a negative impact on dimensional stability.
Although adopting a slow start-up procedure can prevent such problems - by introducing temperature gradually - it can take several hours and paper mills cannot afford the lost production and revenue. Instead, the solution lies in astute bearing selection.
To counter the effects of temperature, NSK analysed the mechanism of inner ring fracture and established a strength evaluation method that subsequently led to the development of the proprietary TL specification. The type of steel used in these bearings is case-carburised using a special method of heat treatment that attains both high raceway surface hardness and dimensional stability under high temperatures. Importantly, the strength of the inner ring is increased sufficiently to better resist hoop stress, even at temperatures up to 200°C.
The resistance of inner rings that meet the TL specification is higher than the resistance of inner rings made from bainitic steel or bearing steel, while the surface hardness of the rolling surface is greater than the hardness of rolling surfaces made from bainitic steel or case-hardened steel. These factors underpin the ability of TL bearings to provide longer service life when used on calenders, guide rolls and smoothing rolls, for example.
A case in point involves a major paper mill that was experiencing problems with its calender rolls, where multiple cracks were developing on the inner rings of the roll bearings. Frustrated by up to 12 failures annually, which led to excessive downtime and maintenance, the mill invited NSK´s team of expert engineers to investigate and resolve the issue. As part of NSK´s Added Value Programme AIP, a comprehensive application review was commenced.
The NSK specialists soon discovered that the standard spherical bearings being used in the calender roll did not feature carburised inner rings, leaving them susceptible to the high heat of the application, and cracking of the inner rings. It was therefore recommended that the paper mill switch to NSK spherical roller bearings with TL technology. The innovative chemical steel composition and greater resistance to hoop stress and cracks, doubled operating life and reduced the cost of replacement bearings and downtime. Over a five-year period since the change was made, the paper mill has saved around €430,000.
NSK spherical roller bearings with TL technology have been in operation on dryer cylinders and other papermaking machinery rolls since 1994, with no problems reported. Today, over 100 different TL bearing sizes/types are produced, helping a wide range of customers achieve better and more cost-effective performance. In addition, to accommodate bearings for Yankee dryer rolls, NSK can offer large TL series self-aligning roller bearings with diameters up to 1,360 mm.

‘Let’s Talk Tissue’— A Panel Discussion About the Tissue Industry’s Challenges and Opportunities in the Age of COVID-19
Just a few short months ago at the start of the COVID-19 pandemic in the United States, news reports were filled with scenes of pandemonium at supermarkets and shelves emptied of cleaning supplies and — most critically — bathroom tissue. Tales of selfish tissue hoarders and desperate tissue searchers for that formerly bountiful commodity were daily media fodder.
The pandemic crisis placed enormous pressure on the tissue supply chain. But the sector proved to be remarkably resilient, and the pandemic has actually accelerated the pace of change within the industry. To assess the lasting impact of COVID-19 on the tissue business, Tissue World magazine hosted an online panel discussion June 23 with four industry experts.
Moderated by Jonathan Roberts, conference chair and content advisor for Tissue World, the panel included Kim Underhill, group president of Kimberly-Clark North America; Brian Allen director of cyber advisory services for EY, USA; Udaiyan Jatar, founder of Blue Earth Network, USA; and Ivo Kool, senior product development manager, tissue, paper, nonwovens for Sam’s Club, USA.
The discussion has been edited for length and clarity.
Roberts began the session by noting the panelists all came from North American companies. “That’s not a coincidence,” he noted, “As this event was born out of Tissue World Miami, which was postponed from March and is due to take place in November of this year.”
Roberts then posed his first broad question: “How is the tissue business responding in this extraordinary time?”
Kimberly-Clark’s Underhill noted three areas that have been challenging and required significant leadership: “One being, first and foremost, the safety and well-being of our people and keeping our mills running. We quickly moved into implementing safety protocols — masks, social distancing, temperature checks and the like. A lot of factories had to shut down, but our goal was to keep it running.
“The second challenge was the unprecedented demand,” said Underhill. “There are lots of theories about this hoarding of bathroom tissue, and why bath tissue and towels versus other categories. The clearest explanation was that people felt like they needed a little sense of control. All of a sudden something we take for granted in North America became something you could not imagine life without.
“The demand escalated very fast and the challenge became we were just out of stock, and it wasn’t just Kimberly-Clark, the industry was challenged because of the increase in demand, and we still see that, particularly in the U.S.
“The last challenge was how can we work with our retail partners to fix the supply chain. We realized there were parts of the supply chain we had to rework because it had never seen such extreme and quick consumer demand, which opened up a lot of challenges but also a lot of opportunities in thinking about our supply chain going forward.”
“From the beginning of March to the end of April I’d say purchases almost doubled and then slowly went down to about half,” said Kool of Sam’s Club. “It was quite amazing. A couple of trucks would arrive, we’d unload them, and the product would be gone within an hour or two because people would get on the phone and say, ‘Hey, it’s in town!’ And off everyone would go and buy it.
“But I really have to say for our private brand business, our vendors supported us unbelievably well,” Kool continued. “I mean, everyone pulled out all stops.”
Roberts asked Jatar of Blue Earth Network how industries beyond tissue responded to the pandemic.
“The big companies did a really good job, the best processes I’ve seen,” said Jatar. “They’ve done a really good job about keeping communication going, building public trust and managing personal health and business health. Trust-building and empathy are pretty important.
“The second thing is while I know we are talking about COVID, we have to consider what happened with the Black Lives Matter movement that highlighted the big gaps between the haves and the have nots,” he said. “Companies are recognizing that words are not enough, and there’s a greater tendency to take action now more than ever before.”
“The best organizations are really taking action, supporting their employees, whether it’s with childcare, flexibility in hours or developing diverse talent,” Jatar noted. “And there are opportunities for companies to say we want to be the most diverse and have the best talent and extending their support to Black people.
“And lastly, there’s a push to develop innovation — especially among smaller companies,” he said. “They are innovating product and the supply chain. They are looking through the lens of the future, when people are going to expect more transparency in the supply chain, more justice in the supply chain, when they are going to expect new technologies that address health and sanitation. These companies are innovating from the ground up rather than just fixing legacy systems.”
Roberts asked Allen of EY what kinds of security issues companies and employees were facing during this new period of working remotely.
“We’ve definitely seen a ballooning of threats,” said Allen. “Which is fairly typical when criminals see a fresh opportunity. And it’s coming from organized crime and different state actors. We are all working in a different environment and the biggest weaknesses we’re seeing is employees not being aware of threats.
“One, we have to recognize we are working in a different environment,” Allen continued. “Two, the actors are very sophisticated. They are getting very good at their game. We’re seeing very complicated phishing scams that are exploiting different vulnerabilities — they are selling personal protective equipment, they are offering advice from WHO and doctors, they are exploiting e-commerce.
“Security firms are keeping executives better informed about these risks so they can find the right balance between risk and reward, and can better maneuver in this new environment,” he noted. “But that information about risks needs to be more timely and more in-depth.”
The discussion moved on to the positive lessons learned from the coronavirus crisis.
“There has been an awakening of an awareness of the systemic failures of our economy and our society that were inherent before the COVID crisis,” said Jatar. “A crisis tends to shine a spotlight on your weakest connection, and one of them has been short-termism in the management of culture and gender across all kinds of organizations. There’s been an awakening of appreciation for workers that we didn’t see before.
“And there’s a greater appreciation of the changes that come about by remote working, from improved communications to greater sustainability in work surroundings and a greater appreciation for our human ability to connect online and collaborate,” he said. “Organizations are taking advantage of social distancing and remote working to develop bigger and better ideas and better processes through online collaboration.”
“This crisis has been a gift that has given us an opportunity to accelerate some changes we have wanted to do for a very long time,” said Underhill. “Internally, in the tissue business, SKU management is very important, and one of the things we learned that will be a lasting impact is SKU simplification. In some of our businesses we have cut SKUs by over 70% and that has enabled us to get 15% to 20% improvement in capacity.
“Because the demand was so high, we had no choice but to make some difficult choices,” she said. “And we found that those choices weren’t so bad after all. I see that as sort of a mind-set shift going forward.
“I don’t think any of us would have said we could hold our business together while working from home for over three months,” said Underhill. “But we have. It’s changed the way we connect. I’ve heard people talking about how we’re more engaged, more accessible.”
Roberts asked what transformations we might see in the wake of COVID-19 in terms of consumer behavior, trends and business operations.
“I think we’ll see a more holistic approach,” said Allen. “Rather than looking at risk management as different silos, such as crisis management, information security or business security, we’re seeing a lot of alignment in risk practice to be more coordinated as we move through digitalization.
“One, there’s tremendous overlap in these practices,” he continued. “Two, there are great benefits in getting consistent and timely reporting. And three, we’re really starting to see that these risk assessments need to go deeper into the organization, and some of that is being driven by digitalization. And the demand and speed of digitalization is so significant that the risk practice, whether that’s cyber or IT risk, needs to be provided to business leaders throughout the organization so they can continuously make informed risk-based decisions.”
Roberts: “What changes in consumer behavior are likely to be most impactful and most enduring in the wake of the crisis?”
“We talk a lot about B2C, business-to-consumer, but I think now we are lot more C2B, consumer-to-business, with consumers telling us through their online behaviors and research what values matter to them,” said Jatar. “In this demonetized world, companies have to offer something more than product features and attributes to distinguish themselves. They need to come up with an X-factor that transcends their competitors.
“I’m seeing companies recognizing that consumers and society at large want a lot more out of business than just business,” he said. “They expect businesses to be a part of the community. Organizations that are taking the lead and engaging with Black Lives Matter are also businesses that are creating more equitable feelings for their employees and their customers. There are a couple of value areas where I’m seeing organizations really starting to build a relationship with the B2C and C2B interconnection to really differentiate themselves. But they need to translate those values into action. I think transparency is going to be the big trend going forward because in the digital world there is no place to hide. The companies that take the lead in transparency and build trust will get ahead of their competitors.”
Roberts: “What role does tissue play in a positive human future?”
“All of us are going to become more conscientious, aware and concerned about cleaning and germ control, whether that’s on your person, your automobile, your home or your office,” said Underhill. “I think this is a great opportunity for the tissue world to not only think about our products today, but where we can invent and create innovations that can actually protect at a greater level of confidence.
“I suspect that innovation is going to allow all of us to really gain confidence in protecting ourselves, our family and our environments more than ever before,” she said. “Companies that can invent in this space and create a point of differentiation with real tangible, clinical evidence that you can prevent germs, I think that’s going to be a significant opportunity for the tissue industry.”
Roberts then asked about attracting talent — is that going to be different and is it going to be a bigger challenge in the future?
“The positive thing is rethinking the way we work for the next generation,” said Underhill. “The next generation wants more flexibility, they want to work when they want and where they want, and I believe the former emphasis on visibility in the office, hours in the office — that’s completely reframed by this whole experience, and that’s not important anymore.
“We’re much more focused on the outcomes and how people are working,” she continued. “I’m very excited to see how we carry this forward, and I’m just going to say we’re not going back. We will definitely have much more flexible arrangements for our employee base, particularly our staff operations, in the future. We just have to figure out how to do it. We don’t have the answers yet, but we are definitely not going back to where we were on March 12.”
Tissue World 2020 is currently scheduled for Nov. 11-13, 2020, at the Miami Beach Convention Center.

ABB launches latest digital solution for total control over wet end operations to maximize productivity and profit
ABB Wet End Control offers process stabilization, variability reduction and performance optimization for all paper, board and tissue manufacturers
ABB has just launched the latest generation of its Advanced Process Control (APC) to provide complete digital control over wet end operations, optimizing productivity and profit for paper mills globally.
Wet End Control — an ABB Ability™ APC solution for paper mills — stabilizes the wet end process and reduces variability by controlling, monitoring and optimizing retention performance. It uses a multivariable model predictive control approach to predict future wet end process behavior, making automatic adjustments to stabilize ash levels, reduce white water consistency variability and minimize chemical and filler dosages.
This results in improved machine runnability by helping to reduce sheet breaks, and accelerating grade changes and break recovery. Papermakers can then track performance from the wet end to the final sheet. It is available as a subscription-based service delivered via ABB Ability™ Collaborative Operations, with structured remote monitoring and expert analysis of control performance for sustainable results.
In addition to its impact on productivity, Wet End Control helps to minimize raw material, chemical costs and broke usage, ultimately reducing the environmental impact and leading to lower steam consumption and increased energy savings.
“We know that continuous monitoring of wet end operations is crucial to driving process improvements,” said Ramesh Satini, global product manager for Pulp & Paper Control Systems, ABB. “We developed our Wet End Control solution to address this need by automatically managing targets and implementing cost efficiencies within process constraints. By adopting this ABB service, mills will benefit from ongoing insight and collaboration to optimize stability for long-term gains and minimized operator interventions.”
Wet End Control is part of a fully integrated quality measurement, control and optimization solution that works seamlessly with ABB Ability 800xA control system or a third-party alternative (via OPC interface). ABB’s latest APC platform allows dynamic model adaption to capture varying process dynamics for tighter control, while optimally working within operational parameters to maximize the economic gain. The solution is suitable for all mills seeking a quality measurement, control and optimization solution that enables paper specifications to be met at the lowest possible cost.
How to measure tissue and nonwovens mill machinery performance with real time analytics
Tissue and nonwovens mills rely primarily on the performance of their machinery to ensure the manufacturing of a high-quality product in a reasonable time and at optimal productivity. If this machinery is not running at peak efficiency or if it breaks down, production can slow down or stop altogether.
Yet, the equipment and machinery in a mill is subjected to extreme conditions on a daily basis. Machines in the mill are exposed to things like significant temperature variations and ongoing wear and tear that can impact their performance over time.
In the past it was difficult, if not impossible, to detect small dips in machinery performance simply because the human eye can’t detect small changes in things like machine vibration or speed. By the time a lag in performance was noticeable, the machine was often already at a point of needing repair or would break down entirely. This is one of the biggest causes of lost productivity in the mill. Fortunately, with today’s technology, it is possible to perform real time analytics, allowing mill staff to know the performance level of their machinery at all times.
Measures of Machine Performance
Improving the performance and productivity of fixed assets is the best way to improve shareholder returns. Over the years, a number of key performance indicators (KPIs) have been developed to measure machine performance. Of these KPIs, Overall Equipment Effectiveness (OEE) has become an industry standard for the tissue and nonwovens mill.
OEE measures three categories within the mill: equipment availability, equipment performance, and product quality. When it comes to machine performance in the tissue and nonwovens mill, the focus is specifically on equipment availability, the amount of time the machine is actually up and running, and equipment speed.
While it is easy to see when a machine is running or not, it isn’t always easy to understand why it has stopped running or to see this downtime coming. When it comes to machine speed, it is not possible to detect small changes in that speed simply by looking at it. In the past, we simply did the best we could and dealt with machine downtime. However, today we have new technology that makes real time analytics possible.
The Role of Industry 4.0
Industry 4.0 is the key to ensuring optimal performance of mill machinery. It offers a combination of the Industrial Internet of Things (IIoT), data management, and artificial intelligence (AI)/machine learning that make it possible to continuously monitor every machine in every plant, as well as overall plant operations.
Pivotal to the measurement of machine performance in real time is IIoT. IIoT requires the installation of thousands of sensors and cameras along the production line. Every single machine will have dozens or hundreds of sensors that are continuously measuring every single aspect of the machine during operation. These sensors can gather data in a digital format from parts of the machine that mill workers cannot monitor adequately. They can sense changes in the machine’s operation that the human eye can’t even detect, all in real time.
The sensors on each machine are part of a company-wide network of sensors and devices that are connected to the cloud. As the data are collected, they are gathered and fed into AI software that can provide real-time analytics. Machine learning allows the machinery to make adjustments in real time and the system can alert staff of anomalous readings and let them know when maintenance is required.
A Bird’s Eye View with Real Time Analytics
How does all this improve machine performance? Since data are constantly flowing in from sensors sensitive enough to detect the slightest changes in machine performance, real time analytics:
- provides a closeup view of the different variables affecting machine performance;
- determines the probability that the machine will break down;
- anticipates and schedules predictive maintenance.
In other words, when something isn’t working at peak efficiency and speed, the system will pick up on that. Maintenance can then be scheduled before those minor anomalies become big enough to cause the machine to slow down or break down entirely. In addition, with such detailed data from every part of every machine, a tissue and nonwovens mill can tweak environmental and machine settings to ensure the highest possible speed a machine can be run at without compromising product quality. This pushes machine performance to its optimal state, and when you can accomplish this, equipment availability and equipment speed scores increase and your overall OEE score goes up.
Final Word
The technology available today has made Industry 4.0 possible, and with that, real time analytics is also possible. With the ability to collect data continuously and while a machine is in operation, the chances of a machine going offline or slowing down are significantly reduced. This provides tissue and nonwovens mills with much tighter control over all aspects of their operations and allows them to automate their processes so they can increase operational efficiency and make better product with less waste and in less time. Since time is money, this is the ideal situation for any tissue and nonwovens company competing in the market today.
