Rotor Clip E-43ST Zd External E Style Retaining Ring

Product Description

The ROTOR CLIP E-43ST ZD is an external E style retaining ring designed to secure components on a 7/16 inch (0.4375 inch) shaft. The ring seats in a groove with a 0.343 inch diameter and holds position through three prongs that grip the shaft groove. Made from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, it provides corrosion resistance in light-duty service environments. Ring thickness measures 0.035 inches and hardness is rated at 37-43 HRC. This ring is installed by mechanics, millwrights, and maintenance technicians wherever a low-profile external ring is needed to retain bearings, pulleys, or other shaft-mounted components.

This retaining ring is suited for light machinery, motors, pumps, and other rotating assemblies where an external E style ring fits standard shaft and groove dimensions. The compact profile makes it a common choice in tight-clearance assemblies across industrial, HVAC, and equipment maintenance applications. The minimum order quantity is 100 pieces, making it appropriate for shop stock or production use.

Installation Notes

Installation and removal require external retaining ring pliers sized for the ring diameter; using incorrect tools can distort the prongs and compromise retention. Always relieve any shaft load and de-energize the equipment before servicing shaft-mounted components. Inspect the shaft groove for burrs or wear that could affect seating and the ring's rated holding performance. Dispose of any ring that has been removed and reinstalled multiple times, as repeated cycling can reduce prong integrity.
