External Snap Ring, 1-1/2"

The SRE112 External Snap Ring, 1-1/2" is a precision retaining ring designed to secure components on a 1-1/2 inch shaft, helping keep bearings, gears, bushings, and other parts exactly where they belong. Made from durable spring steel with a corrosion-resistant black phosphate finish, this external snap ring fits into a machined groove on the outside of a shaft to prevent axial movement while allowing easy installation or removal with snap-ring pliers. Simple, reliable, and surprisingly strong for something that looks like a tiny steel horseshoe—it’s one of those small parts that quietly keeps big machines behaving properly.
