Ring Specs
(D) Free Diameter: 2.79 +0.08 / -0.08 mm.
(t) Thickness: 0.64 +0.05 / -0.05 mm.
(b) Radial Wall:
Groove Specs:
(B) Application Diameter: 4.0 mm.
(G) Groove Diameter: 3.05 +0.10 / -0.10 mm.
(W) Groove Width: 0.74 +0.15 / -0.00 mm.
Groove Depth: 0.46 mm.
Other Specs
Approximate Weight per 1000: 0.136 kg.
(C1) Clearance Diameter When Sprung Into Groove:9.91mm.
(Z) Minimum Edge Margin:0.91mm.
(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) * (3.96 mm.) * (0.46 mm.) * (310 MPa) * 3.14 ] / 2		440N
(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 3

Equation:
Pr = [ Cf * B * t * Ss * pi ] / K
    = [ (0.5) * (3.96 mm.) * (0.64 mm.) * (827 MPa) * 3.14 ] / 3		1,085N
