Other Specs

Approximate Weight per 1000:
(GAPmin) Gap Minimum:0.840in.
(ND) Notch Depth (+.000 / -.030 "):0.140in.
(NW) Notch Width (Ref.):0.156in.
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 45,000 psi. Calculated using a safety factor (K) of 4

Equation:
Pg = [ B * d * Ys * pi ] / K
    = [ (4.500 in.) * (0.120 in.)* (45,000 psi) * 3.14 ] / 4
19,075lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material1: Carbon Spring Steel (SAE 1060-1095). Shear Strength of Ring Material (Ss): 153,000 psi. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (4.500 in.) * (0.109 in.) * (153,000 psi) * 3.14 ] / 3

1Calculation assumes Carbon Steel for ring material, but Carbon Steel not necessarily available for all parts or sizes.
78,548lbs.
