This needle roller bearing carries a single row of rollers guided by a standard cage, providing a compact radial cross-section without an inner ring, to DIN 617/ISO 1206. Outside diameter is 37.0 mm and width is 30.0 mm, with a net mass of 96.9 g. The limiting speed reaches 16900 1/min, while the reference speed is 9500 1/min. The bearing has no sealing, so lubrication must be supplied and maintained externally, and the mounting surface must be protected from contamination. The absence of an inner ring means the shaft seat itself serves as the raceway, requiring a hardened and ground shaft surface. The standard cage guides the needle rollers evenly, supporting the stated speed ratings under radial load in applications where axial space is limited.
