Also known as constant-section rings, these rings have open ends and a profile that does not taper like other external retaining rings. Use them with linear bearings on support rail shafts. Open rings with flat-tip retaining ring pliers (sold separately), pass them over the end of a shaft, and release to spring into the groove. The black-phosphate finish is mildly corrosion resistant in dry environments.
