Other Specs
Approximate Weight per 1000: 0.091 kg.
(C) Free Outside Diameter:9.53mm.
(C1) Clearance Diameter When Sprung Into Groove:9.91mm.
(Vmax) Bow Height Maximum:0.89mm.
(Vmin) Bow Height Minimum:0.64mm.
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 310 MPa. Calculated using a safety factor (K) of 2

Equation:
Pg = [ Cf * B * d * Ys * pi ] / K
    = [ (0.333) * (2.79 mm.) * (0.39 mm.) * (310 MPa) * 3.14 ] / 2		169N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 690 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.333) * (2.79 mm.) * (0.25 mm.) * (690 MPa) * 3.14 ] / 3		169N
