This needle roller bearing carries radial loads in a compact cross-section, with an outside diameter of 55.0 mm and a width of 20.0 mm. It has a single row of rollers, a standard cage, and a net mass of 110.0 g. The bearing is sealed on both sides with lip seals (2RSR), and the limiting speed is 6400.0 1/min. The double-sided sealing keeps grease inside the bearing and prevents dirt and moisture from entering, which supports maintenance-free operation once initially lubricated. The standard cage guides the needle rollers to maintain even load distribution across the row. Given its slim width relative to the outside diameter, this bearing suits applications with limited radial installation space where a full complement of needle rollers is required for load capacity within the stated speed limit.
