| | (C) Clearance Diameter When Sprung Into Bore: | 0.400 |  | in. |  | (C1) Clearance Diameter When Sprung Into Groove: | 0.440 |  | in. |  | (V) Overall Bow Height: | 0.063 |  | in. |  | (Vtol) Bow Height Tolerance (+/-): | 0.007 |  | 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) * (0.688 in.) * (0.022 in.) * (45,000 psi) * 3.14 ] / 2
 | 1,283 |  | lbs. |  |  |  | (Pr) Theoretical Thrust Load Capacity - Ring Shear: Notes: Ring Material: 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) * (0.688 in.) * (0.035 in.) * (150,000 psi) * 3.14 ] / 4
