Rotor Clip SE-98ST Pa E Style Retaining Ring 63/64 in

Product Description

The ROTOR CLIP SE-98ST PA is an external E-style retaining ring designed to seat in a precision-machined external groove on a 63/64-inch (0.9844-inch decimal) shaft. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, this three-prong ring provides a reliable axial stop for shafts used in mechanical assemblies. The ring carries a hardness rating of 47-52 HRC, delivering the spring-back and retention force expected in high-cycle industrial and OEM applications. Groove diameter is 0.835 inches with a groove width of 0.056 inches and a ring thickness of 0.050 inches. Licensed machinists, maintenance technicians, and OEM assembly personnel are the typical installers.

This retaining ring is suited for use in rotating shaft assemblies, gearboxes, motor shafts, pump assemblies, and similar mechanical components requiring a compact external groove fastener. The E-style profile allows side-loading installation without removing the shaft from the assembly, which makes it practical in confined or hard-to-reach locations. It is dimensioned to the inch measurement system and conforms to SAE 1060-1090 and UNS G10600-G10900 standards, as well as ISO 13485:2015 quality management requirements.

Key Features

• Groove diameter of 0.835 inches with a close tolerance range of 0.000 to 0.003 inches
• Ring thickness of 0.050 inches with a tolerance of -0.002 to 0.002 inches for consistent fitment
• Conforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards

Compatibility

Designed for external groove installation on 63/64-inch (25.00 mm) diameter shafts with a groove diameter of 0.835 inches and groove width of 0.056 inches machined to SAE 1060-1090 retaining ring groove specifications.

Installation Notes

Installation requires external retaining ring pliers sized for E-style rings; standard snap ring pliers used for circlips are not appropriate for the E-style side-load profile. Power down and de-energize any rotating equipment before servicing shaft assemblies. Inspect the groove for burrs or dimensional nonconformance before seating the ring, as an out-of-spec groove can cause improper retention. Follow applicable machinery safety standards and OEM torque specifications for any fasteners disturbed during shaft access.
