Other Specs
Approximate Weight per 1000: 0.120 lbs.
(C) Free Outside Diameter:0.275in.
(C1) Clearance Diameter When Sprung Into Groove:0.290in.
(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) * (0.219 in.) * (0.013 in.) * (45,000 psi) * 3.14 ] / 2		100lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 120,000 psi. Calculated using a safety factor (K) of 4

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.5) * (0.219 in.) * (0.025 in.) * (120,000 psi) * 3.14 ] / 4		257lbs.
