THK RA and RAV Series Thin Cross Roller Ring
The THK RA Series is a compact version of the RB Series, built with extremely thin outer and inner rings. It’s the right choice when the swiveling unit in your design needs to stay light and small. Model RA uses a spacer retainer for a low friction coefficient and stable rotational torque, with a basic dynamic load rating from 5.10 kN to 25.8 kN. Model RAV is the full roller type, suited to low speed rotary use under higher loads and available in all metal specifications, rated from 7.24 kN to 41 kN.
Its separable outer ring design supports outer ring rotation, making it a practical option for compact swivel joints and lightweight rotary mechanisms.
