Other Specs

Approximate Weight per 1000: 1.452 kg.
(C) Free Outside Diameter:20.57mm.
(C1) Clearance Diameter when Sprung into Groove:21.08mm.
(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
    = [ (0.25) * (12.70 mm.) * (1.32 mm.) * (310 MPa) * 3.14 ] / 2
2,042N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 1,034 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.25) * (12.70 mm.) * (1.07 mm.) * (1,034 MPa) * 3.14 ] / 3

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