This needle roller bearing carries a solid outer ring without an inner ring, giving an outside diameter of 22.0 mm at a net mass of 25.6 g. The light series design keeps the radial section low while the standard cage guides the needle rollers and maintains their spacing under load. Rated limiting speed reaches 24600 1/min, with a reference speed of 18300 1/min. The absence of an inner ring allows the bearing to run directly on a hardened and ground shaft, reducing radial space requirements compared to designs with a full inner ring. The standard cage keeps friction and heat generation moderate, supporting operation up to the stated reference speed under normal lubrication conditions. This construction suits applications where a shaft can serve as the running surface and where radial load capacity is needed within a compact envelope.
