Picture of machines using NSK roller bearings for paper machines at a papermaking factory.

In recent years, the papermaking industry has been making great advances in enhancing the speed and the width of coverage of papermaking machines with the objective of boosting productivity.

To reduce the amount of downtime caused by unexpected problems, we have developed a range of roller bearings for paper machines that meet our customers’ demands. 
As one of the global technology leaders, we understand and provide solutions to the challenges found in the Paper Industry.  With products specifically designed to support equipment utilised in high temperature, and highly contaminated environments, NSK's bearings allow longer life and higher limiting speeds which result in greater productivity.
Being a manufacturer and supplier of products is not enough in today’s World. That is why we see ourselves as your reliable partner, providing a broad range of support activities to help you enhance your business & bottom line.

We work together with you on-site to develop individual solutions for smooth, efficient and profitable production processes in your business.

Operating conditions: Moisture, water ingress and high speeds

Levels of moisture are high in the wire section. This can result in water penetration and bearing corrosion. Water ingress together with the tendency towards ever-greater speeds can lead to premature bearing failure and production stoppages.

NSKHPS series of bearings for very high speeds

To overcome these common problems, NSKHPS range for breast rolls and egoutteur as well as wire drive, wire guide and wire suction rolls also include components such as spherical roller bearings for the paper industry which have a 20% higher limiting speed and last up to twice as long compared to standard products. These paper industry bearings have a special cage design and optimised outer ring surface. Highly accurate precision grades (P55) are also available.


Wire Section

Operating conditions: Low / heavy loads and high speeds

The paper industry demands reliable operation and long service life. Press nips are subject to very heavy loads, while suction press rolls reach very high speeds – up to 2,500 m/min will be possible in the future. Choosing the wrong bearings for paper making machines can quickly lead to raceway damage.

Spherical roller bearings for extremely high loads and speeds in shoe presses

In collaboration with a renowned supplier of equipment for paper machines, NSK has developed, tested and released spherical roller bearings with optimised internal design which are suitable for high, current and future, line speeds in shoe presses

Our Innovations:
Triple Ring Bearings
NSKHPS Series Spherical Roller Bearings



Operating conditions: Very high temperatures, high speeds, heavy loads

Temperatures of up to 150°C are common at the dry end of paper machines. They are also subject to high axial forces and tensile strain. In this demanding environment, the bearing inner ring can crack, causing machine downtime.

TL series spherical roller bearings for high temperatures

NSK’s TL (“Tough & Long life”) series was developed specifically for drying rolls in paper making machines, which run at very high temperatures. Together with special heat treatment, the chemical composition of the steel used makes the inner and outer rings extremely resistant to wear and cracking. This  can dramatically reduce downtime and maintenance costs.

TL Series Spherical Roller Bearings
Cylindrical Roller Bearings with Aligning Rings
NSKHPS Series Spherical Roller Bearings

Dry end

Operating conditions: High temperatures, extremely high speeds, heavy loads

Calender rollers are subject to heavy loads and high speeds which can rapidly cause spherical roller bearings to fatigue. Expansion of the bearing inner ring due to heat can lead to cracks which ultimately result in machinery failure.

TL RUB bearings with enhanced running accuracy for high speed and high temperature operation

Thanks to their improved running accuracy and resistance to temperatures up to 200°C, NSK TL RUB bearings are the ideal floating bearing solution for these demanding conditions and future performance upgrades. The bearings’ design enables the calender rolls to expand thermally with no restraints.
