Other Specs

Approximate Weight per 1000: 2.000 lbs.
(C) Free Outside Diameter:0.991in.
(C1) Clearance Diameter When Sprung Into Groove:1.010in.
(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) * (0.875 in.) * (0.043 in.) * (45,000 psi) * 3.14 ] / 2
1,329lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: 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
    = [ (0.5) * (0.875 in.) * (0.042 in.) * (150,000 psi) * 3.14 ] / 4

*Shear Strength of Material value is for Carbon Spring Steel material only.
2,163lbs.
