THK RA-C Series Cross Roller Ring

The THK RA-C Series shares the same main dimensions as the RA Series, but its outer ring uses a single-split structure instead of a separable design. This gives the outer ring high rigidity on its own, so the RA-C can be used for outer ring rotation as well as inner ring rotation, which the standard RA Series can’t do. It carries a basic dynamic load rating from 5.10 kN to 25.8 kN and a basic static load rating from 7.19 kN to 54.7 kN.

This makes the RA-C a flexible option when your design might need outer ring rotation later, without giving up the thin, lightweight profile of the RA Series.
