0.200 7300 7000 a Thrust Load Safety Factors: Ring, 4; groove, 2. Groove wall thrust loads are for grooves machined in cold-rolled steel with a tensile yield strength of 45,000 psi; for other shaft materials, the thrust load varies proportionally with the yield strength. Source: Industrial Retaining Rings, 2000 Series. All dimensions are in inches. Depth of groove d = ( D − G )/2. Standard material: carbon spring steel (SAE 1060-1090). Thickness indicated is for unplated rings; for most plated rings with shaft sizes less than 1.000 inch, the maximum thickness will not exceed the minimum groove width (W) minus 0.0002 inch; for larger rings, the ring thick ness may increase by 0.002 inch. Groove Maximum Bottom Radii: For shaft diameters less than 0.500 inch, 0.005 inch; for shaft sizes 0.500 through 1.000 inch, 0.010 inch; all larger sizes, 0.015 inch. Ring Free Diameter Tolerances: For shaft sizes 0.125 through 0.188, +0.002, − 0.004; for sizes 0.219 through 0.437, +0.003, − 0.005; for sizes 0.500 through 0.625, ± 0.006; for sizes 0.687 through 1.000, ± 0.007; for sizes 1.125 through 1.500, ± 0.008; for sizes 1.750 and 2.000, ± 0.010. Ring Thickness Tolerances: For shaft sizes 0.125 through 1.500, ± 0.002; for sizes 1.750 and 2.000, ± 0.003. Groove Diameter Tolerances: For shaft sizes 0.125 through 0.188, ± 0.0015; for sizes 0.219 through 0.437, ± 0.002; for sizes 0.500 through 1.000, ± 0.003; for sizes 1.125 through 1.500, ± 0.004; for sizes 1.750 and 2.000, ± 0.005. Groove Width Tolerances: For shaft sizes 0.125 through 0.188, +0.002, − 0.000; for sizes 0.219 through 1.000, +0.003, − 0.000; for sizes 1.125 through 2.000, +0.004, − 0.000.
