Operating conditions: Moisture, water ingress and high speeds

Moisture levels are high in the wire section which results in water penetration and bearing corrosion. Water ingress together with the tendency towards even-greater speeds can lead to premature bearing failure and loss of production.

NSKHPS series of bearings for very high speeds

NSK has devloped products to overcome these common issues found in paper manufacturing, NSKHPS Spherical Roller Bearings offer a 20% higher limiting speed and last up to twice as long compared to standard products. NSKHPS offer a special cage design and optimized outer ring surface, with highly accurate precision grades (P55) also available.


Wire Section

Operating conditions: Low / heavy loads and high speeds

The paper industry demands highly reliable operation and long service life from their bearings. Press rolls are subject to very heavy loads, while suction press rolls reach very high speeds. Improper bearing selection for paper applications like these 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 optimized 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
Spherical Roller Bearings with CAM cage



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

Temperatures up to 150°C are common in the dry end of paper machine. They're subject to high axial forces and tension. Due to these demanding environments, the bearings inner ring can crack, causing machine downtime and loss of production.

TL series spherical roller bearings for high temperatures

NSK’s TL (Tough & Long life) series was developed specifically for dryer rollsrunning at very high temperatures. Combined with special heat treatment, the chemical composition of the steel used makes the inner and outer rings extremely resistant to wear and cracking,dramatically reducing downtime and maintenance costs.

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

Calender rolls are subject to heavy loads and high speeds which can rapidly cause fatigue in spherical roller bearings. High heat of the application causes expansion of the bearing inner ring leading to cracks, ultimately resulting in bearing failure.
