Rotor Clip SH-25SS B100 External Retaining Ring 1/4 in

Product Description

The ROTOR CLIP SH-25SS B100 is an external retaining ring designed to secure components on a 0.25-inch diameter shaft by seating into a precision-machined external groove. Manufactured from 15-7 Grade 632 stainless steel to the AMS-5529 and UNS S15700 standards, the ring delivers a hardness of 47 to 52 HRC with a zinc finish for added corrosion resistance. The groove diameter is 0.23 inches with a ring thickness of 0.025 inches, making it suited for tight-tolerance fastening applications in mechanical assemblies. Machinists, maintenance technicians, and assembly professionals install these rings where reliable axial retention is needed in compact hardware configurations.

This external retaining ring is used in industrial, mechanical, and precision assembly applications where a 1/4-inch shaft requires axial component retention. Its 15-7 stainless steel construction makes it appropriate for environments demanding corrosion resistance and high hardness. Typical install scenarios include rotating assemblies, pneumatic tools, motors, pumps, and specialty mechanical equipment where standard carbon steel rings are inadequate. This part is compliant with ISO 13485:2015, making it suitable for use in regulated manufacturing environments such as medical device assembly.

Key Features

• 15-7 Grade 632 stainless steel construction rated to 47-52 HRC hardness for demanding service conditions
• Zinc finish provides additional corrosion resistance on the ring exterior
• Groove diameter of 0.23 inches with a groove width of 0.029 inches for precise shaft fitment
• Free outside diameter of 0.45 inches allows installation in space-constrained assemblies
• Meets AMS-5529, UNS S15700, and ISO 13485:2015 standards
• Ring thickness of 0.025 inches with tight tolerance of plus or minus 0.002 inches for consistent axial load performance

Compatibility

Designed as an OEM-style external retaining ring for 1/4-inch diameter shafts requiring a 0.23-inch groove diameter. Suitable for mechanical assemblies specifying AMS-5529 or UNS S15700 compliant fasteners.

Installation Notes

External retaining rings of this type are installed by machinists or assembly technicians using appropriate retaining ring pliers or applicator tooling rated for the ring size. Ensure the shaft groove is free of burrs and debris before seating the ring to prevent improper seating or ring damage. De-energize and lock out any associated mechanical or electrical equipment before servicing components retained by this ring. Verify groove dimensions match the specified 0.029-inch width and 0.01-inch depth before installation to ensure full ring engagement.
