Other Specs
Approximate Weight per 1000:
(GAPmax) Maximum Gap:36.50mm.
(GAPmin) Minimum Gap:22.23mm.
(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
    = [ (165.10 mm.) * (2.03 mm.) * (310 MPa) * 3.14 ] / 4		81,705N
(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
    = [ (165.10 mm.) * (2.36 mm.) * (1,055 MPa) * 3.14 ] / 3		430,584N
