Rotor Clip SH-12BC B100 External Retaining Ring 1/8 in

Product Description

The ROTOR CLIP SH-12BC B100 is an external retaining ring designed to secure components on a 1/8-inch (0.125-inch) shaft. It seats in a precision groove with a 0.117-inch groove diameter and holds a ring thickness of 0.010 inches. Manufactured from Beryllium Copper to ASTM B197 and UNC C17200 standards, the ring provides strong retention force in compact assemblies. A zinc finish adds corrosion resistance. This part ships in minimum order quantities of 100 units and is intended for installation by mechanical assemblers, maintenance technicians, and industrial tradespeople working on precision shafted assemblies.

This external retaining ring is suited for use on small-diameter shafts in precision mechanical assemblies across industrial, HVAC, and electromechanical applications. The 1/8-inch shaft size is common in motors, actuators, valve stems, and similar components where a low-profile external ring is required to retain a bearing, bushing, or housing. The ring is compliant with ISO 13485:2015, making it appropriate for use in quality-managed manufacturing environments.

Key Features

• Fits 1/8-inch (0.125-inch) shaft diameter with 0.117-inch groove diameter
• Beryllium Copper construction per ASTM B197 and UNC C17200
• Zinc-plated finish for added corrosion resistance
• Ring thickness of 0.010 inches with tight tolerance of plus or minus 0.001 inches
• Hardness rated at 84-86 HRC for reliable retention under load
• ISO 13485:2015 compliant — suitable for quality-managed production environments

Compatibility

Designed as an OEM-style external retaining ring for 1/8-inch diameter shafts requiring a groove diameter of 0.117 inches and a groove width of 0.012 inches.

Installation Notes

External retaining rings of this size require retaining ring pliers sized for small-diameter external rings — standard snap ring pliers may damage the ring or groove on this scale. Always relieve shaft load and de-energize any associated motor or actuator before removing or installing the ring. Verify groove diameter and width against the specifications before installation to ensure proper seating and retention. Wear appropriate eye protection, as small-diameter rings can become projectiles during installation or removal.
