Abstract
In a large antifriction bearing consisting of two bearing races and at least two track systems disposed therebetween each having a rolling element row which rolls on associated tracks of the bearing races, one rolling element row (4, 11) is of a different material to the other rolling element row (5, 12) to enable bearing properties such as clearance or bias, rotation resistance and wear compensation to be influenced without external action or interventions on the bearing and also to permit compensation of different track tolerances at the periphery (FIG. 1).
Claims4
Large antifriction bearing comprising two bearing races and at least two track systems disposed therebetween and each having a rolling element row rolling on associated tracks of the bearing races, characterized in that the one rolling element row (4, 11) is of a material different to the other rolling element row (5, 12), said other rolling element row (5, 12) is equipped with rolling elements of plastic, and said plastic rolling elements are larger than the accommodation space of the associated track system.
