Provides radial guidance under load through a full complement of needle rollers running in a solid outer ring without ribs, an inner ring being a separate mounting part. Bore diameter is 25.0 mm, outside diameter 40.0 mm, width 17.0 mm, net mass 84.112 g. The bearing supports a limiting speed of 15100.0 1/min and a reference speed of 8100.0 1/min. The absence of ribs on the outer ring gives a compact radial section for the given bore-to-outside-diameter ratio, which suits mounting positions where axial space around the needle set must stay minimal. As a needle roller bearing without an integral inner ring, it requires a hardened and ground shaft surface to serve as the running track, so shaft tolerance and surface finish at the seat directly affect running accuracy and service life. No sealing is integrated, so lubrication and contamination protection must be provided by the surrounding housing design.
