Other Specs
Approximate Weight per 1000:
(m) Material Thickness:2.34mm.
(N) Ring Number of Turns:2.000
(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 = [ B * d * Ys * pi ] / K
    = [ (323.85 mm.) * (7.29 mm.) * (310 MPa) * 3.14 ] / 2		1,149,924N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1070-1090). Shear Strength of Ring Material (Ss): 827 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (323.85 mm.) * (4.75 mm.) * (827 MPa) * 3.14 ] / 3		1,332,003N
