Cross-Roller Ring Standard USP-Grade Series Models RB and RBV
Its rotation accuracy is of ultra precision grade, which excels the world’s highest classes of accuracy defined by standards such as JIS2 class, ISO class2, DIN P2 and AFBMA ABCE9.
Products with spacer retainers (Model RB-USP) have a low friction coefficient and demonstrate highly stable rotational torque. Full-Roller products (Model RBV-USP) are suited to low-speed rotary operations with higher loads, and they are also compatible with all-metal specifications.
