This needle roller bearing carries a full complement of needle rollers guided by a TV cage, without an inner ring, giving an outside diameter of 10.0 mm and a net mass of 3.41 g. The light series design (XL) keeps the radial section low while the TV cage keeps the rollers evenly spaced and reduces friction losses. Limiting speed is rated at 39000 1/min, with a reference speed of 54000 1/min. The lack of an inner ring means the bearing runs directly on a hardened and ground shaft, which reduces radial section further and suits applications where the shaft itself serves as the raceway. The TV cage design allows a high radial load capacity for the given envelope while maintaining smooth running at the stated speed range. As supplied without seals, relubrication and contamination protection must be provided externally, and mounting requires attention to correct shaft tolerance to maintain the intended running accuracy.
