Other Specs
Approximate Weight per 1000: 3.100 lbs.
(C) Clearance Diameter When Sprung On To Shaft:1.040in.
(C1) Clearance Diameter When Sprung Into Groove:1.000in.
(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
    = [ (0.5) * (0.781 in.) * (0.024 in.) * (45,000 psi) * 3.14 ] / 2		662lbs.
(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
    = [ (0.667) * (0.781 in.) * (0.042 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.		2,576lbs.
