THK RB25040UUCC0P5 Cross Roller Bearing
RB25040UUCC0P5 is a standard-type crossed-roller bearing with a separable outer ring and integrated inner ring. Cylindrical rollers are arranged perpendicularly in 90° V‑grooves via a retainer, allowing the bearing to support radial, axial, and moment loads simultaneously with high rigidity and precision.
