Other Specs

Approximate Weight per 1000: 0.054 kg.
(C) Free Outside Diameter:6.99mm.
(C1) Clearance Diameter When Sprung Into Groove:7.37mm.
(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
    = [ (0.5) * (5.56 mm.) * (0.33 mm.) * (310 MPa) * 3.14 ] / 2
445N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material* (Ss): 827 MPa. Calculated using a safety factor (K) of 4

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.5) * (5.56 mm.) * (0.64 mm.) * (827 MPa) * 3.14 ] / 4

*Shear Strength of Material value is for Carbon Spring Steel material only.
