Documentation
Description
SHI retaining rings are axially assembled external circlips with inverted lugs and are part of Rotor Clip’s tapered section retaining ring line. Functionally similar to standard SH rings, the inverted lugs reduce how far the lugs extend beyond the shaft circumference, making them suitable for applications with minimal radial clearance.
