Other Specs
Approximate Weight per 1000: 53.372 lbs.
(C) Clearance Diameter When Sprung onto Shaft:3.740in.
(C1) Clearance Diameter When Sprung into Groove:3.583in.
(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) * (3.032 in.) * (0.059 in.) * (45,000 psi) * 3.14 ] / 2		15,166lbs.
(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) * (3.032 in.) * (0.098 in.) * (150,000 psi) * 3.14 ] / 4		41,985lbs.
