The following is Internal Retaining Snap Ring Sizes and Groove Design Chart for sizes .250 to 1.500

Retaining Ring Grove Dimensional Requirements

Internal Retaining ( Snap ) Ring Sive Designations

(All data is in inches.)

Reference: Industrial Retaining Snap Rings, 3100 Series.

All dimensions are in inches. Depth of groove d = (OD-ID)/2. Thickness indicated is for unplated rings; for most plated rings, the maximum ring thickness will not exceed the minimum groove width (S) minus 0.0002 inch. Standard material: carbon spring steel (SAE 1060-1090).

Ring Free Diameter Tolerances: For shaft sizes 0.125 through 0.250, +0.002, -0.004; for sizes 0.276 through 0.500, +0.002, -0.005; for sizes 0.551 through 1.023, +0.005, -0.010; for sizes 1.062 through 1.500, +0.010, -0.015; for sizes 1.562 through 2.000, +0.013, -0.020; for sizes 2.062 through 2.500, +0.015, -0.025; for sizes 2.559 through 5.000, +0.020, -0.030; for sizes 5.250 through 6.000, +0.020, -0.040; for sizes 6.250 through 6.750, +0.020, -0.050; for sizes 7.000 and 7.500, +0.050, -0.130.
