THK RA-C Single-Split Cross-Roller Ring
THK RA-C is a thin cross-roller ring with a single-split outer ring. Its rigid outer ring allows the unit to be used for outer ring rotation. The design also provides high rigidity and accurate rotary motion.
The RA-C uses cylindrical rollers arranged in a cross pattern. This allows the bearing to handle radial, axial and moment loads in one unit. Its thin design helps reduce the size of rotary mechanisms.
THK RA-C is available with shaft diameters from 50 to 200 mm. Models include RA5008C through RA20013C. Radial basic dynamic load ratings range from 5.10 to 25.8 kN, while basic static load ratings range from 7.19 to 54.7 kN.
