RNA6908 Double Row Needle Roller Bearing 48x62x40mm Without Inner Ring High Load For Reducer Hydraulic Motor

• RNA6908 is an open double row machined outer ring needle roller bearing without inner ring, with standard dimensions 48×62×40 mm. Manufactured from premium GCr15 bearing steel, it adopts solid machined outer ring and steel stamping cage to hold two rows of needle rollers evenly.Without an independent inner ring, the hardened and ground shaft surface directly serves as the rolling raceway, greatly saving radial installation space. It features ultra-high radial load capacity and structural rigidity, suitable for compact installation positions subjected to heavy radial loads. The open design facilitates grease replenishment and routine maintenance, widely applied in various industrial heavy-duty transmission devices.
