The Rotor Clip SH-43ST MCD is a high-quality external retaining ring designed for 7/16" shaft diameters, constructed from carbon spring steel with a cadmium-plated finish. This axially assembled ring is engineered to securely hold assemblies in place, preventing axial movement and ensuring operational stability. Its tapered section design allows for uniform contact within the groove, accommodating higher thrust loadings and providing a more substantial shoulder compared to constant section or spiral retaining rings. The cadmium plating offers enhanced corrosion resistance, extending the ring's service life and maintaining performance in demanding environments. Supplied in a convenient pack of 50 pieces, the SH-43ST MCD is ideal for applications requiring reliable axial retention and durability.
