(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) * (1.438 in.) * (0.044 in.) * (45,000 psi) * 3.14 ] / 2	4,470		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) * (1.438 in.) * (0.050 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.	8,466		lbs.
