1/ T = Thickness "T" applies to unplated rings. For corrosion resistant steel and plated rings, +.002 should be added to the maximum tolerance, i.e., ±.002 should be +.004/-.002.
2/ FIM = (Full Indicator Movement) is the maximum allowable deviation of concentricity between the groove and the shaft.
3/ K = Maximum diameter when the ring is properly seated in the groove (design reference dimension).
4/ C = Actual clearance diameter when the ring is sprung over the shaft prior to installation into the groove (design reference dimension).
5/ R and CH = Radii or chamfers allowable on parts to be retained by the rings. Thrust loads of rings, retaining parts with corner radii or chamfers (see note "3 (g)" on page 7).
Requirements:
1. Classification: Retaining rings furnished under this standard shall be Type I, Class 10 of the procurement specification, MIL-R-21248.
2. Material:
(a) Carbon steel, grade 1060 thru 1095 (UNS G10600 thru G10950) in accordance with ASTM A568/A568M or ASTM A684/A684M.
(b) Corrosion resistant steel in accordance with SAE-AMS 5520 (UNS S15700).
(c) Beryllium copper alloy number 170 (UNS C17000) or alloy number 172(UNS C17200) in accordance with ASTM B194.
3. Hardness:
