Types of Retaining Rings
Types of Retaining Rings
- External Retaining Rings
External Retaining Rings:- External retaining rings sit in the grooves on the exterior of shafts of any size. The areas of the ring that protrude out from the shaft hold it in place.
- Internal Retaining Rings/Housing rings
Internal Retaining Rings/Housing rings:- Housing Rings, or HO Rings, are axially assembled internal retaining rings that are made from zinc plated spring steel and installed with needle-nose pliers into a housing or bore. These tapered section type rings have a taper design that allows the ring to maintain constant pressure against axles, gears, and bearings inside machinery housings to prevent slippage.
- E-Clips
E-Clips:- An E-ring or ring clip is a type of circlip that`s pushed on or off a grooved shaft without the need for a special tool.
- External Push-On Rings
External Crescent Rings:- External crescent rings are smaller shoulder retaining rings applied radially to shaft grooves where the lugs of other rings would present a clearance issue. The crescent ring easily snaps into place forming a narrow, uniform concentric shoulder. The absence of teeth and deep set equals lower thrust load ratings over E-clips. Steel construction for strength and durability. Install using an applicator.

- Round Retaining Rings
Round Retaining Rings:- Round wire snap rings are designed for rounded grooves in external and internal shaft or bore applications. They are known for their ability to hold tight tolerances.
- Spiral Rings
Spiral Rings:- These rings are coiled from wire and used for large size or short run applications. Available in internal, external, tabbed, and dished in a variety of materials and finishes. The steel construction provides strength and durability. They are designed to absorb vibrations from electronic devices.
- External Poodle Rings
External Poodle Rings:- External Poodle Rings Are Designed to Hold Assemblies In Place For Machinery and Equipment Applications. The rings feature wide lobes or ears for extra surface area retention against retained parts or equipment. Steel construction provides strength and durability. Install using an applicator or standard pliers and screwdriver.
- Internal Push-On Rings
Internal Push-On Rings:- Push-On Retaining Rings are ideal when the shaft you are working with does not have any internal grooves. The teeth or prongs each “push” against the inside of the shaft to stay in place. Not only do Push-On Retaining Rings require no groove in the shaft, they are also the ideal choice for lower force jobs.
