Rotor Clip SH-34ST Zd External Retaining Ring 11/32 in

Product Description

The ROTOR CLIP SH-34ST ZD is an external retaining ring engineered for use on shafts with an 11/32 inch (0.3438 inch decimal) diameter. Made from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, this ring seats into a precision groove to secure components axially on a shaft. Ring thickness measures 0.025 inches, groove width is 0.029 inches, and groove depth is 0.011 inches. Hardness runs 69.5 to 73 HRC, providing the retention strength needed in demanding mechanical assemblies. Licensed tradespeople and industrial maintenance technicians working on motors, pumps, gearboxes, and similar rotating equipment are the primary installers.

This retaining ring is suited for light-duty to medium-duty shaft assemblies where a compact, low-profile external ring is required. Its 0.321 inch groove diameter and 0.309 inch free diameter allow controlled installation with standard snap ring pliers. The zinc plating provides corrosion resistance appropriate for indoor mechanical environments and general industrial applications. Minimum order quantity is 100 pieces, making this ring practical for production runs and maintenance parts inventories alike.

Compatibility

Designed as a standard external retaining ring for shafts with an 11/32 inch diameter groove profile conforming to SAE 1060-1090 fastener standards.

Installation Notes

Installation is performed with snap ring pliers sized for external rings; using the correct plier tip size prevents ring distortion and ensures proper groove seating. Relieve mechanical load and de-energize or lock out any rotating equipment before removing or installing retaining rings. Inspect the shaft groove for burrs or damage before installation, as groove irregularities can prevent full ring seating and compromise retention. Rings should not be reused after removal, as repeated spreading can affect dimensional tolerances and hardness integrity.
