Sealed Backup Long-life Roll Bearings
Sealed Back Up Long Life Bearings were specifically designed for Sendzimir mills in Iron and Steel works. Due to the SAC steel and optimized seal design these bearings achieve long life under high-speed operating conditions. With excellent lubrication properties and sealing performance to combat issues associated with oil-air lubrication, this bearing innovation enables enhancement of bearing life under contaminated lubrication conditions.
