This needle roller bearing supports radial loads in a compact single-row design without an inner ring, machined to DIN 617/ISO 1206. Outside diameter is 39.0 mm, width 17.0 mm, and net mass is 51.91 g. The limiting speed reaches 15300 1/min, with a reference speed of 8600 1/min, and the bearing is fitted with a standard cage. The bearing has no sealing, so lubrication and contamination protection must be provided by the surrounding housing design. As it lacks an inner ring, the shaft seat itself must serve as the inner running surface, requiring a hardened and ground journal. The RNA49/22-XL design allows a radially compact arrangement where axial space is limited but full needle roller complement is needed for load capacity.
