Description

This needle roller bearing carries a solid inner ring and a full complement of needle rollers, giving high radial load capacity within a compact cross-section. Bore diameter is 45.0 mm, outside diameter 68.0 mm, and net mass 276.9 g. The RSR designation indicates a lip seal fitted on one side, while the other side remains open. The one-side lip seal keeps contaminants out of the raceway on the sealed face and retains lubricant on that side, so orientation during installation matters if the open side faces a source of dirt or moisture. Due to its dimension series 49 design, the bearing suits applications needing high radial rigidity in limited radial space, where a solid inner ring simplifies shaft mounting and handling.
