This needle roller bearing carries a solid outer ring with machined needle rollers running directly on the shaft, giving a radial section suited for applications where housing space is limited. Outside diameter is 130.0 mm, net mass 0.82 kg, limiting speed 4200 1/min and reference speed 2750 1/min. The cage is of standard design, guiding the needle rollers evenly around the raceway. Without an inner ring, the bearing requires a hardened and ground shaft surface to serve as the raceway, so shaft tolerance and surface hardness directly affect running accuracy and service life. The standard cage keeps rolling elements aligned at the stated speed ratings, while the absence of built-in sealing means external protection must be provided for the mounting position. Grease or oil lubrication can be applied depending on the surrounding design, with relubrication intervals set according to the actual operating speed relative to the reference value.
