Cross roller bearing is a compact structural bearing with rollers arranged orthogonally between the inner and outer rings. Adopting a structure with orthogonal arrangement of rollers as bearings to support the rotating axis of the robot and achieve optimal performance. It has the characteristics of compact structure, high rigidity, high precision, and easy installation.

The variety of cross roller bearing products is very rich and complete, covering various sizes. The standard outer ring split RB series, CRB full roll series, and inner ring split RE series are suitable for machine tools, large robots, and general industrial equipment; Thin RA type, with small cross-sectional size, suitable for small and medium-sized robot joints and electronic and electrical equipment automation devices such as semiconductors; In order to achieve higher stiffness and accuracy, the CRBH model with integrated inner and outer rings has been developed based on the first two products; Ultra thin ringback tone type, specially developed for precision small equipment; The RU type has high rigidity and mounting holes, which can simplify the structure of the bearing seat.
