ABSTRACT:
The bearing has an expanded load zone for better distribution of the load among the rollers, if used, or balls, if used, and allows the bearing to perform better under conditions of misalignment. As an example, the bearing may include a non-rotating ring which has an elastomer of non-uniform thickness bonded to it. The non-uniform thickness of the elastomer will cause a bearing race to go out of round when under load to the point that each roller or ball in approximately 180.degree. of the load zone has the same load, thus reducing maximum rolling element stress. Plastic, lead, alloys, or babbitt materials may be used as an alternative to elastomeric material.
