RE-USP and REV-USP Series Cross Roller Ring

The RE-USP and REV-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.

These models share the same main dimensions as the standard RE/REV series, while providing exceptionally high rotational accuracy, making them suitable for precision equipment where outer-ring rotation accuracy is critical.

Model RE-USP, equipped with spacer retainers, offers a low friction coefficient and highly stable rotational torque for smooth and precise rotation.

Model REV-USP is a full-roller type designed for low-speed rotary motion under higher loads and is also compatible with all-metal specifications, making it suitable for demanding applications requiring ultra-high accuracy.
