(G) Groove Diameter: 2.602 +0.006 / -0.006 in. (W) Groove Width: 0.103 +0.005 / -0.000 in. Groove Depth: 0.074 in. Other Specs Approximate Weight per 1000: 42.500 lbs. (C) Clearance Diameter Expanded Over Shaft: 3.450 in. (C1) Clearance Diameter & Guaging Diameter Seated in Groove: 3.310 in. (Pg) Theoretical Thrust Load Capacity - Groove Yield: Notes: Yield Strength of Groove Material (Ys): 45,000 psi. Calculated using a safety factor (K) of 2 Equation: Pg = [ Cf * B * d * Ys * pi ] / K     = [ (1) * (2.750 in.) * (0.074 in.) * (45,000 psi) * 3.14 ] / 2 14,377 lbs. (Pr) Theoretical Thrust Load Capacity - Ring Shear: Notes: Ring Material1: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 150,000 psi. Calculated using a safety factor (K) of 4 Equation: Pr = [ Cf * B * t * Ss * pi ] / K     = [ (1) * (2.750 in.) * (0.093 in.) * (150,000 psi) * 3.14 ] / 4 1Calculation assumes Carbon Steel for ring material, but Carbon Steel not necessarily available for all parts or sizes. 30,114 lbs.
