Cross Roller Slewing Bearing

Cross cylindrical roller slewing bearings are a type of crossed roller bearing that is made up of two races and a single row of crossed cylindrical rollers. They are made up of an inner ring, outer ring, single row of cross-placed rollers, cage or isolation block, and sealings. Cross cylindrical roller slewing bearing is composed of an inner ring, outer ring, single row of cross-placed rollers, cage or isolation block, sealings, and other parts.
