Rotor Clip SH-125SS B100 External Retaining Ring 1-1/4 in

Product Description

The ROTOR CLIP SH-125SS B100 is an external retaining ring designed to secure components onto shafts by seating into a machined groove. It fits a 1-1/4 inch shaft diameter with a groove diameter of 1.176 inches and a ring thickness of 0.050 inches. Manufactured from 15-7 grade 632 beryllium copper stainless steel conforming to AMS-5529 and UNS S15700, this ring offers high hardness in the 47-52 HRC range. A zinc finish provides added corrosion resistance. Machinists, maintenance technicians, and mechanical assembly professionals install these rings in shaft-and-housing assemblies across industrial and mechanical applications.

This external retaining ring is suited for use in precision shaft assemblies where a reliable axial stop is required. The 15-7 stainless steel construction makes it appropriate for environments where corrosion resistance and high hardness are both critical factors. It is commonly installed in industrial machinery, rotating equipment, and mechanical subassemblies. The zinc finish provides additional surface protection in moderate service environments. This ring is sold in a package quantity of one with a minimum order quantity of two units.

Installation Notes

External retaining rings are installed by mechanical technicians using appropriate external snap ring pliers sized for the ring diameter. Before installation, verify the shaft groove dimensions match the ring specifications to ensure proper seating and axial retention. Always inspect the groove for burrs or damage that could affect ring seating or load capacity. Follow applicable machinery safety lockout and tagout procedures before disassembling or reassembling shaft components.
