Description
This needle roller bearing carries a solid inner ring and full complement of needle rollers arranged in dimension series 49, giving high radial load capacity within a compact cross-section. Bore diameter is 40.0 mm, outside diameter 62.0 mm, and net mass is 235.56 g. Sealing is designated RSR, with a lip seal fitted on one side of the bearing. The one-sided lip seal keeps contamination out of the roller path on that face while allowing grease or oil lubrication to be maintained inside the bearing. With the solid inner ring, this design supports precise radial guidance and is suited to applications requiring a compact bearing with high radial load capacity in a limited installation space, where sealing is only needed on one side of the unit.
