Rotor Clip SH-237ST Zd External Retaining Ring 2-3/8 in

Product Description

The ROTOR CLIP SH-237ST ZD is an external retaining ring engineered to secure components on a 2.375-inch shaft. It seats in a precision groove and holds assemblies axially without additional fasteners. The ring is formed from SAE 1060-1090 carbon steel, heat-treated to a hardness of 47-52 HRC for reliable load resistance. A yellow zinc dichromate finish provides corrosion protection. With a groove diameter of 2.239 inches, a ring thickness of 0.078 inches, and a groove width of 0.086 inches, this ring meets tight dimensional tolerances suitable for industrial and mechanical drive applications. Licensed tradespeople and mechanical assemblers install this type of hardware during shaft assembly and overhaul work.

This external retaining ring is suited for use on shafts with a 2.375-inch diameter where a grooved retaining method is required. Typical applications include pump shafts, gearbox assemblies, motor shafts, and rotating equipment found in HVAC, plumbing, and industrial drive systems. The zinc dichromate coating makes it appropriate for environments with moderate moisture exposure. It is sold individually with a minimum order quantity of 2 units.

Compatibility

Designed as an OEM-style external retaining ring for 2.375-inch shafts requiring a grooved seat; confirm groove diameter, width, and depth against shaft specifications before installation.

Installation Notes

External retaining rings of this type are installed by machinists or licensed mechanical technicians using snap-ring pliers sized for external rings. Shut down and de-energize all rotating equipment before servicing shafts or replacing retaining hardware. Verify that the shaft groove dimensions match the ring specifications prior to installation to prevent ring failure under load. Do not reuse a ring that has been removed, as deformation during removal compromises its holding capacity.
