Rotor Clip SH-131ST Zd External Retaining Ring 1-5/16 in

Product Description

The ROTOR CLIP SH-131ST ZD is an external retaining ring designed to secure components on a 1-5/16 inch (1.3125 inch decimal) shaft. Made from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, it provides corrosion resistance and a hardness rating of 47-52 HRC for dependable retention under load. The groove diameter is 1.232 inches with a tolerance of -0.004 to +0.004 inches, and the ring thickness is 0.05 inches. Licensed HVAC technicians, plumbers, electricians, and mechanical trades use external retaining rings like this one when assembling or servicing rotating shafts, gearboxes, pumps, and motor assemblies.

This retaining ring fits shafts with a 1-5/16 inch diameter and a groove width of 0.056 inches. It is suited for light industrial and trade applications including pump shaft assemblies, fan hubs, motor shafts, and similar rotating equipment found in HVAC, plumbing, and general mechanical service work. The zinc-plated finish makes it appropriate for moderately corrosive environments. Package quantity is 1 ring per package with a minimum order quantity of 10 units.

Installation Notes

External retaining rings require snap ring pliers sized for the ring diameter; do not use general-purpose pliers, as this can distort the ring or cause it to slip. Shut down and de-energize all equipment before disassembling any shaft assembly. Verify groove dimensions against the ring specifications before installation to confirm a proper seat. Follow applicable mechanical codes and equipment manufacturer guidelines for shaft assembly torque and preload requirements.
