Description
This needled roller bearing carries a full complement of rollers on a solid outer ring, with a bore of 20.0 mm, an outside diameter of 37.0 mm and a width of 30.0 mm, giving a net mass of 137.0 g. The limiting speed reaches 16900 1/min, with a reference speed of 8900 1/min, and the design corresponds to the XL series with reinforced load capacity for its envelope size. Radial internal clearance is set to CN (Group N), giving standard running clearance suited for general shaft mounting without preload adjustment. The cage is of standard design and the bearing is supplied without sealing, so external protection against contamination and separate lubrication and sealing arrangements must be provided at the housing. The narrow width relative to bore and outside diameter makes this bearing suitable where radial load capacity is needed within a compact axial envelope.
