The RW Series features a standard imperial outer ring and an extended inner ring. This extension provides a precise axial offset, acting as a built-in spacer against other shaft components. Without the flange of the FRW series, the RW series is designed for clean, high-precision fits in standard cylindrical bores while maintaining simplified spacing.
