Contact Stresses in Rolling Bearings | SpringerLink

10/4/2016· Abstract The Hertzian pressure (normal stress) in the contact zone between the ball/roller and raceways causes a plastic deformation of the ball/roller contour. In the contact area, the oil-film thickness is nearly constant at the height h c and reduces to the height at h min at the outflow of the contact zone (cf. Chap. 4).
