This needle roller bearing carries a solid inner ring with a full complement of needle rollers running on an outer ring track, in dimension series 49. Bore diameter is 40.0 mm and outside diameter is 62.0 mm, with a net mass of 237.76 g. Sealing is provided by lip seals on both sides (2RSR), integrated on both faces of the outer ring. The compact cross-section of dimension series 49 gives high radial load capacity within a limited outside diameter, suitable for applications where radial space is restricted but rigidity is required. The double lip seal arrangement retains grease and excludes contaminants from both sides, allowing operation without additional external sealing. As a solid needle roller bearing, it requires the shaft to serve as the running surface unless a matched inner ring is fitted separately, and it should be mounted with correct axial guidance since it only accommodates radial loads.
