Other Specs
Approximate Weight per 1000: 0.330 lbs.
(GAP) Standard Gap:0.364in.
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 45,000 psi. Calculated using a safety factor (K) of 4

Equation:
Pg = [ B * d * Ys * pi ] / K
    = [ (0.438 in.) * (0.010 in.) * (45,000 psi) * 3.14 ] / 4		154lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1095). Shear Strength of Ring Material (Ss): 138,000 psi. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (0.438 in.) * (0.039 in.) * (138,000 psi) * 3.14 ] / 3		2,467lbs.
