RB-USP and RBV-USP Series Cross Roller Ring

The RB-USP and RBV-USP Cross-Roller Ring Series deliver ultra-precision rotational accuracy, exceeding the world’s highest accuracy classes defined by JIS Class 2, ISO Class 2, DIN P2, and AFBMA ABEC 9.

Model RB-USP, which uses spacer retainers, provides a low friction coefficient and highly stable rotational torque, making it ideal for ultra-precision rotary applications.

Model RBV-USP is a full-roller type designed for low-speed rotary motion under higher loads. It is also compatible with all-metal specifications, making it suitable for demanding, high-load environments requiring exceptional accuracy.
