This needle roller bearing carries load through a single row of rollers guided directly against the housing bore, without an inner ring, giving an outside diameter of 25.0 mm at a net mass of 23.5 g. The XL designation indicates the light series with reinforced roller complement for the given envelope size. Cage execution is standard, and the bearing is rated for a limiting speed of 22600 1/min with a reference speed of 15300 1/min. Because there is no inner ring, the shaft seat itself must act as the inner raceway, so shaft hardness and surface finish at that seat need to match raceway requirements. The design keeps radial section low for the given load capacity, and the standard cage guides the rollers evenly around the circumference, supporting the stated speed ratings under continuous operation.
