Long-life Sendzimir Backup Roll Bearings

Cylindrical Roller Bearing, Sendzimir BUR, double-row

These bearings were specifically designed for Sendzimir mills in Iron and Steel works. Due to the SAC steel and an optimised seal design, they achieve long life under conditions of contaminated lubrication and high-speed operating conditions. Their excellent lubricating properties and sealing performance respond to issues associated with oil-air lubrication. 
Also available as STF (Super TF).
