Other Specs
Approximate Weight per 1000:
(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
    = [ (1.260 in.) * (0.036 in.) * (45,000 psi) * 3.14 ] / 4		1,602lbs.
(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
    = [ (1.260 in.) * (0.042 in.) * (138,000 psi) * 3.14 ] / 3		7,643lbs.
