THK RB Series Cross Roller Ring
The THK RB Series Cross Roller Ring is a standard cross roller ring with a separable outer ring, designed for applications requiring precise rotary motion, high rigidity and the ability to accommodate radial, axial and moment loads.
The RB Series uses a spacer retainer between the crossed rollers, providing a low friction coefficient and stable rotational torque. THK offers an extensive size range, from 20 to 1,250 mm inner diameter, covering both compact precision mechanisms and large industrial rotary applications.
When a certain level of rotational accuracy is required, THK specifies the RB Series for inner-ring rotation. The lineup provides basic dynamic radial load ratings from 3.23 to 1,350 kN and basic static radial load ratings from 3.10 to 3,970 kN, depending on the model.
