Abstract
A method is provided for producing a roller thrust bearing having a plurality of rows of rollers, the bearing featuring reduced differential slip, reduced friction and wear, and increased longevity without flaking. The method includes forming a cage to accommodate the rollers, crowning the rollers, and arranging the rollers in pockets such that the rollers held by a pocket have respective end surfaces in direct contact with each other.
