ABSTRACT:
A structural arrangement to restrain skewing of the individual cylindrical rollers which comprise a roller type bearing. At least one of the inner and outer bearing race defining means includes a pair of laterally spaced apart side flanges to partially capture the rollers therebetween with the opposed roller ends each associated with one of the side flanges. At least one of the side flanges is defined by a separate flange member which is selectively movable toward and away from the other side flange. This flange member is urged into engagement with the roller ends associated therewith and causes the rollers to be axially moved so that the roller other ends engage the other side flange. This relationship effects close maintenance of the rollers between the side flanges to prevent roller skewing during bearing use. The means for urging the flange member may advantageously comprise resilient or spring type biasing means as well as fluid pressure. During bearing use, a hydrodynamic lubricant film provides axial pressure to slightly deflect the biasing means and thus accommodate slight separation between the side flanges and roller ends to preclude wear therebetween.
