Other Specs
Approximate Weight per 1000: 0.030 kg.
(C) Clearance Diameter When Sprung onto Shaft:8.79mm.
(C1) Clearance Diameter When Sprung into Groove:8.20mm.
(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) * (4.00 mm.) * (0.10 mm.) * (310 MPa) * 3.14 ] / 2		236N
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1060-1090). Shear Strength of Ring Material (Ss): 690 MPa. Calculated using a safety factor (K) of 4

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (1.2) * (4.00 mm.) * (0.40 mm.) * (690 MPa) * 3.14 ] / 4		1,050N
