Other Specs
Approximate Weight per 1000: 19.360 lbs.
(MaxRPM) Max Allowable Rotations Per Minute (x1000):3.000
(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
    = [ (2.835 in.) * (0.035 in.)* (45,000 psi) * 3.14 ] / 4		3,505lbs.
(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
    = [ (2.835 in.) * (0.079 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.		35,865lbs.
