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.
