Other Specs

Approximate Weight per 1000:
(m) Material Thickness:0.76mm.
(N) Ring Number of Turns:1.000
(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
    = [ (49.20 mm.) * (0.72 mm.)* (310 MPa) * 3.14 ] / 2
17,040N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1070-1090). Shear Strength of Ring Material (Ss): 869 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (49.20 mm.) * (0.79 mm.) * (869 MPa) * 3.14 ] / 3

1Calculation assumes Carbon Steel for ring material, but Carbon Steel not necessarily available for all parts or sizes.
