BENERI® RETAINING RINGS - Reverse Lug Axially Mounting, External for Shafts
External Retaining Rings for Shafts 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 shaft, the portion of the ring extending beyond the groove surface holds an assembly in place, even under loaded conditions. The 2108-5108 family of EXTERNAL, AXIAL MOUNT Retaining Rings are available in shaft diameter sizes between .500 and 3.938 inches, and groove sizes between .468 and 3.734 inches. Ring thicknesses are between .035 and .109 inches. Lugs are "reversed" for use in applications where clearance is minimal; provides smaller radial width and uniform/concentric support towards axis of shaft.
