  • White paper: Thin section bearings save weight and space ...

    When a bearing roller is in contact with raceways, excessive pressure peaks occur at the ends of the contact rectangles. This is called edge loading. Roller and/or raceway profiles are usually crowned to prevent edge loads. Lundberg developed a logarithmic function for a crowned profile. The profile gives an axially uniform pressure distribution.
