Pulp & Paper
The pulp and paper industry continues to make great strides in productivity with enhanced speeds and wider wires. To avoid unexpected downtime, bearings in papermaking machines must be highly reliable.
NSK offers a complete bearing lineup for all roll sections of modern papermaking machines, with specialized solutions that keep production moving.
- Tough Long-Life TL Bearings
Designed specifically for dryers, TL bearings take full advantage of NSK's materials and heat treatment technologies. - NSKHPS™ Spherical Roller Bearings
NSKHPS bearings integrate NSK's unique materials, design knowhow, and manufacturing technologies into a high-performance standard.
Never settling, we continue to pursue ever more reliable bearings that further improve productivity with less waste.
NSK Experience & Technology
Bearings in the dryer rolls of papermaking machines operate under hot conditions due to the high-temperature steam passed through the rolls. This makes bearings in papermaking particularly susceptible to damage including:
- early wear caused by insufficient oil film formation,
- creep from deformation caused by use at high temperatures over long periods, and
- cracks in the inner ring from increased fitting stress due to the difference in temperature between the shaft and ring.
Inner ring cracks in particular are a serious issue that can fully stop production.
NSK is your solution—our TL Series bearings use a special nitrocarburizing treatment to increase the strength of the inner ring and maintain dimensional stability even at high temperatures.
With a trusted track record, TL bearings serve as a market leader in dryer roll bearings.
