The inner ring is solid while the outer ring is split, making it suitable for applications requiring lightweight, compact designs such as robotic and manipulator rotating components. It can accommodate either inner or outer ring rotation. The RA type cross roller bearing offers a high-rigidity, integrated inner and outer ring structure, with corresponding dimensions listed in the CRBH series.
