Features:

Sendzimir bearings are bearings that are mounted in groups on stationary shafts to become support rollers when the outer ring is particularly thick. The pressure on the work rolls is transmitted to the support rollers via the intermediate rollers and to the frame via the saddle system. It is generally used in multi-high cold rolling mill equipment, and can also be used in other occasions.
The backing bearing is a multi-row cylindrical roller bearing, and the accuracy required by the bearing itself is very high, especially the cross-sectional height (T value) from the inner diameter to the outer diameter after eliminating the radial clearance is particularly important, and the T value is controlled within 0.005mm on each shaft, so that the precision of the bearing parts must be very high.
