Rotor Clip SH-25ST Pa B100 External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-25ST PA B100 is an external snap retaining ring designed to seat in a shaft groove and prevent axial movement of assembled components. Made from SAE 1060-1090 spring steel with a phosphate finish, this ring fits a 1/4-inch shaft diameter and a groove diameter of 0.23 inches. The phosphate coating provides a baseline level of corrosion resistance and improves lubrication retention. With a ring thickness of 0.025 inches and a hardness rating of 69.5 to 73 HRC, it delivers the spring-back force and wear resistance expected in light mechanical and industrial fastening applications. Machinists, maintenance technicians, and assembly professionals install this type of ring using snap ring pliers on shafts in motors, pumps, gearboxes, and similar equipment.

This external retaining ring is suited for applications requiring a compact, low-profile fastening solution on 1/4-inch shafts. It is commonly used in light industrial machinery, small motor assemblies, pump shafts, and precision mechanical subassemblies where axial retention of bearings, gears, or collars is required. The minimum order quantity is 100 rings per order, packaged as one unit. Shaft diameter is available in both inch and metric references: 1/4 inch or 6.35 mm.

Compatibility

Designed for use on 1/4-inch diameter shafts requiring an external retaining ring with a 0.23-inch groove diameter. Suitable for standard shaft groove configurations conforming to SAE 1060-1090 and UNS G10600-G10900 fastener standards.

Installation Notes

External snap retaining rings must be installed with appropriate external snap ring pliers to avoid overstressing the ring during spreading. De-energize or lock out all equipment before installing or removing retaining rings on rotating shafts. Inspect the shaft groove for burrs or damage that could prevent proper ring seating. Do not reuse a ring that has been overstressed or visibly deformed during removal.
