Details DrawingSpecifications Comments

Backing bearing is a special cylindrical roller bearing. Multiple backing bearings are mounted on one roll. The external surface of each backing bearing is used as part of the rolling surface. So, it is required that the backing bearings  shall have uniform cross sections. The precision requirements for their parts are very strict.
