Carries radial loads in a compact cross-section without an inner ring, allowing the needle rollers to run directly on a hardened and ground shaft journal. The bearing has an outside diameter of 17.0 mm, a net mass of 10.3 g, and belongs to the light series. It reaches a limiting speed of 29500 1/min and a reference speed of 29000 1/min, and uses a TV cage to guide and space the needle rollers. The XL suffix indicates a modified internal design, and the open construction without an inner ring keeps radial space requirements low while still supporting the stated speed range. Since there is no inner ring, the mounting surface on the shaft must be hardened and ground to the same tolerances normally held by a bearing inner ring, and lubrication (grease or oil) must be supplied directly to the needle roller and cage assembly. The TV cage design keeps the needle roller complement aligned and reduces friction losses at the given speed limits.
