Other Specs

Approximate Weight per 1000: 8.532 kg.
(GAP) Standard Gap:27.38mm.
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 310 MPa. Calculated using a safety factor (K) of 4

Equation:
Pg = [ B * d * Ys * pi ] / K
    = [ (33.32 mm.) * (0.99 mm.)* (310 MPa) * 3.14 ] / 4
8,038N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1060-1095). Shear Strength of Ring Material (Ss): 1,055 MPa. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (33.32 mm.) * (3.96 mm.) * (1,055 MPa) * 3.14 ] / 3

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