E-Style External Retaining Ring, Tapered Section, Radial Assembly, SAE 1060-1090 Carbon Steel, Phosphate Finish, 1/2" Shaft Diameter, 0.042" Thick, Made in US (Pack of 100)
Retaining rings attach to a shaft (external) or install in a bore (internal), creating a shoulder to maintain component positioning within an assembly. While most rings install into a machined groove either on the inside or outside diameter of a shaft, self-locking rings attach to a shaft by using friction from means such as teeth and notches to maintain placement. Retaining rings should fit tightly enough into the groove or onto the shaft so they won't experience any movement.
