Other Specs

Approximate Weight per 1000:
(C) Free Outside Diameter:11.99mm.
(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) * (8.00 mm.) * (0.98 mm.) * (310 MPa) * 3.14 ] / 2
1,250N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 827 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.333) * (8.00 mm.) * (0.79 mm.) * (827 MPa) * 3.14 ] / 3

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