Standard Internal Retaining Ring, Tapered Section, DIN 1.4122 Stainless Steel, Passivated Finish, Meets DIN 472 Specifications, 45mm Bore Diameter, 1.75mm Thick, Made in US (Pack of 5)
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.
