Standard External Retaining Ring, Tapered Section, Axial Assembly, SAE 1060-1090 Carbon Steel, Phosphate and Oil Finish, Meets DIN 471 Specifications, 23mm Shaft Diameter, 1.20mm Thick, Made in US (Pack of 25)
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.
