Internal retaining rings for bores are safety elements for axially mounting universal use. Retaining rings can transmit considerable axial loads between the element of the device which exerts the force and the groove in which the ring is assembled. Once the ring is assembled in the groove of a housing or bore, the portion of the ring extending beyond the groove surface holds an assembly in place, even under loaded conditions. The 2000-5000 family of Internal, Axial Mount retaining rings are available in shaft diameter sizes between 0.250 and 7.500 inches, and groove sizes between 0.268 and 7.840 inches. Ring thicknesses between 0.015 and 0.187 inches.
