External Retaining Ring 61088
The MIDWEST FASTENER 61088 is a steel external retaining ring with a black phosphate finish. It installs on the outside of a shaft to locate components or secure the shaft to a fixed item. This hardware suits maintenance technicians and assemblers who need reliable axial retention in mechanical assemblies. The ring is supplied new and ready for installation.
Black Phosphate Finish
The black phosphate coating provides a layer of corrosion resistance for the steel substrate. This finish helps protect the ring during storage and in operating environments where moisture or light chemical exposure may occur. It also reduces light reflection on the installed part. The coating is integral to the supplied hardware and requires no separate treatment.
Shaft-Mounted Retention
The ring fits into a machined groove on the shaft to create a shoulder that holds adjacent parts in place. It handles axial loads typical for external retaining rings of this standard design. The component is not intended for applications requiring internal bore mounting or for shafts lacking a properly sized groove. Builders needing internal retaining rings or different groove specifications must select a different part type.

Questions about this item
Does the 61088 retaining ring need periodic replacement or lubrication during its service life?
The steel ring with black phosphate finish is a passive mechanical fastener; it has no moving parts, no lubrication requirement and no scheduled replacement interval.
What mechanical limit of the 61088 ring is reached first when the shaft rotates continuously under load?
The ring’s grip on the shaft groove is the limiting factor; if thrust forces exceed the groove’s shear capacity the ring can walk out of its groove.
Does the 61088 ring generate noticeable heat or noise when the shaft runs all day?
The ring is a static metal component; it produces no measurable heat, vibration or audible noise during continuous shaft rotation.
