Sendzimir bearings are bearings that are mounted in groups on stationary shafts when used with particularly thick outer rings to become support roller bearings. 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.
       Sendzimir bearing is a multi-row cylindrical roller bearing, the bearing itself requires a very high precision, especially after eliminating the radial clearance of the inner diameter to the outer diameter of the section height (T value) is particularly important, on each shaft, the T value is controlled within 0.005mm, so that the bearing parts must be very high precision.
