Other Specs

Approximate Weight per 1000: 24.870 lbs.
(GAP) Standard Gap:1.125in.
(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
    = [ (1.375 in.) * (0.043 in.) * (45,000 psi) * 3.14 ] / 4
2,088lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1095). Shear Strength of Ring Material* (Ss): 153,000 psi. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (1.375 in.) * (0.172 in.) * (153,000 psi) * 3.14 ] / 3

*Shear Strength of Material value is for Carbon Spring Steel material only.
37,873lbs.
