VSH-206ST PA, 2-1/16 In. Diameter, 0.078 Thick, External Beveled Retaining Ring in Carbon Steel, Phosphate Manufactured by Rotor Clip
External beveled rings look exactly like the basic external rings, only they have a 15* angle on the outer edge. This combines with a complementary groove angle to eliminate end play by wedging itself between the groove and the retained part.
