Other Specs
Approximate Weight per 1000:
(Gap Max) Maximum Free Gap:17.45mm.
(Gap Min) Minimum Free Gap:11.10mm.
(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
    = [ (46.99 mm.) * (1.22 mm.) * (310 MPa) * 3.14 ] / 4		13,949N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: 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
    = [ (46.99 mm.) * (1.57 mm.) * (1,055 MPa) * 3.14 ] / 3		81,701N
