Shape and Dimensions of Retaining Ring-E Type n m 2d 1d b d t D H Note(1): Maximum value for D is the maximum value on the pin's circumference, and the minimum value for D is the average of D1, D2 and D3. Reference: t is in accordance with JSMA (Japan Spring Manufactures Association Standard)No.6. Unit: mm Free In Use Reference: Typical shape is shown. Note(1): d should be measured with a limit plug gauge. Note(2): For thickness (t) = 1.6mm, the value of 1.5mm may be substituted for on the right side of the formula, for the time being. In this case, m must be 1.65mm. Reference: The recommended dimensions of the applicable shaft are given here for reference.
