RA Type Cross Roller Bearing, Outer Ring Split Type, for Inner Ring Rotation

This model is a compact version achieved by reducing the thickness of the inner and outer rings of the RB type. Similarly, the outer ring is divided into upper and lower axial parts, while the inner ring is a single piece, making it suitable for applications where lightweight and limited space are required.

【High Rotation Accuracy】

Since spacer retainers are installed between the vertically arranged rollers, the tilting of rollers or mutual friction between rollers is prevented, thereby avoiding an increase in rotational torque. Additionally, compared to conventional types using sheet metal retainers, there is no occurrence of one-sided contact or locking phenomena in the rollers. Even when preload is applied, stable rotational motion can be achieved.Furthermore, due to the structure where the inner or outer ring is split into two parts, preload can be adjusted, enabling high-precision rotational motion.
