Description
BSH retaining rings are axially assembled external circlips with a bowed profile and are part of Rotor Clip’s tapered section retaining ring line. Installed into a groove on a shaft, the bowed design applies a preload to compensate for accumulated tolerances and maintain external axial retention over the specified range.
