  • Patent number: 6682226
    Abstract: A cylindrical roller bearing having preloading capability is disclosed. A preloading mechanism having an annular groove having a deformable raceway and which is configured to accept a segmented support ring is incorporated into either the outer race of the inner race. A plurality of fasteners are installed in holes in the flanges of the annular groove and into the segmented support ring. By tightening the fasteners, the flanges of the annular groove are tightened against the segmented support ring, thereby deforming the deformable raceway from an arcuate shape to a flat or slightly crowned shape, placing a preload on the rollers of the bearing. The amount of preload is determined by the angular and dimensional interface between the segmented support ring and the annular groove.

  • Patent number: 6666585
    Abstract: A unitized cage for cylindrical roller bearings wherein the inner raceway of the bearing configuration may be the rotating or stationary shaft component and the outer raceway of the bearing configuration may be the rotating or stationary housing component. Thus, a bearing configuration can be generated without the need for a separate inner or outer race having inner or outer raceways. The unitized cage comprises a cage nest having end face axial projections and a cage finger ring having fingers which engage the end face axial projections to lock the cage nest into position on the cage finger ring. A plurality of cylindrical rollers can be positioned within the cage pockets of the cage nest prior to the assembly of the cage nest with the cage finger ring to generate a cylindrical roller bearing.
