Other Specs
Approximate Weight per 1000: 1.637 kg.
(C) Clearance Diameter When Sprung Into Bore:17.40mm.
(C1) Clearance Diameter When Sprung Into Groove:19.81mm.
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 310 MPa. Calculated using a safety factor (K) of 2

Equation:
Pg = [ Cf * B * d * Ys * pi ] / K
    = [ (1.2) * (27.99 mm.) * (0.70 mm.) * (310 MPa) * 3.14 ] / 2		11,218N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 1,034 MPa. Calculated using a safety factor (K) of 4

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (1.2) * (27.99 mm.) * (1.19 mm.) * (1,034 MPa) * 3.14 ] / 4		32,550N
