This needle roller bearing carries radial loads in a compact cross-section without an inner ring, matching directly onto a shaft. It has an outside diameter of 37.0 mm, a width of 17.0 mm, and a net mass of 55.595 g, built to DIN 617/ISO 1206 as a single-row design with a standard cage. The limiting speed is 16900 1/min, with a reference speed of 9900 1/min. The bearing has no sealing, so lubrication and contamination protection must be provided externally, and grease or oil selection should account for the running speed values given. With no inner ring, it allows a compact radial arrangement where the shaft surface itself acts as the inner running track, and the standard cage guides the needle rollers for even load distribution across the single row.
