Other Specs

Approximate Weight per 1000:
(m) Material Thickness:0.092in.
(N) Ring Number of Turns:2.000
(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 = [ B * d * Ys * pi ] / K
    = [ (9.500 in.) * (0.215 in.)* (45,000 psi) * 3.14 ] / 2
144,302lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1070-1090). Shear Strength of Ring Material (Ss): 120,000 psi. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (9.500 in.) * (0.187 in.) * (120,000 psi) * 3.14 ] / 3

1Calculation assumes Carbon Steel for ring material, but Carbon Steel not necessarily available for all parts or sizes.
223,128lbs.
