In cross roller bearings, cylindrical roller due at 90 ° to each other are arranged vertically through the isolation block V-shaped groove raceway, so cross roller bearings can bear radial load, axial load and moment load, etc. load more direction. Cross cylindrical roller bearing turntable composed of two races. Compact, light weight, high manufacturing precision, small assembly space for installation of high precision roller 1: 1 cross arrangement can withstand the axial force and overturning moment large radial force.
