Product parameters

Cross roller bearing is a compact structure bearing with rollers arranged orthogonally between the inner and outer rings. The structure of roller orthogonal arrangement is used as a bearing to support the rotation 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, with a wide range of sizes covered. The standard outer ring splitting RB series and CRB full roller series, as well as the inner ring splitting RE series, are suitable for machine tools, large robots, and general industrial equipment; Thin RA type with small cross-sectional size, suitable for electronic and electrical equipment automation devices such as small and medium-sized robot joints and semiconductors; In order to achieve higher rigidity and precision, the CRBH type with integrated outer and inner rings has been developed based on the first two types of products; Ultra thin CRBT type, specially developed for precision small devices; The RU type with high rigidity and mounting holes can simplify the structure of the bearing seat.
