Is contact stress related to the friction coefficient?

Based on the formula table for the contact stress when a cylinder is in contact with a plane, it is possible to calculate the contact width between the two surfaces. Is this contact width related to the rolling friction coefficient of the cylinder? Is its value equal to 0.5 times the contact width? I hope someone experienced can give me some guidance!!

It’s okay; the contact force is a normal pressure, so no friction is generated. It depends only on the magnitude of the pressure, the radius and length of the cylinder, the elastic modulus, and the Poisson’s ratio.

The friction coefficient has no relation to the contact stress
