This needle roller bearing carries radial loads in a compact cross-section, with an outside diameter of 140.0 mm and a width of 30.0 mm, weighing 0.668 kg. It is built to DIN 617/ISO 1206 as a single-row design without a flanging ring, fitted with a standard cage and no sealing. The limiting speed reaches 3900 1/min, while the reference speed is 2340 1/min. The absence of an inner ring means the shaft surface itself acts as the inner running surface, so mounting requires a hardened and ground shaft seat to the corresponding tolerance. Without sealing, the bearing depends on external protection to keep the running surfaces free of contamination, and lubrication must be supplied and maintained by the surrounding housing design. The standard cage guides the needle rollers evenly around the single row, supporting the stated speed limits under radial loading.
