This needle roller bearing carries a machined outer ring with an outside diameter of 29.0 mm, giving a compact radial section typical of the light series design. The standard cage guides the needle rollers and keeps mass low at 28.2 g. Rated speed limits are set at 12600 1/min for the reference speed and 20600 1/min for the limiting speed, defining the practical rotational range for continuous operation. With no inner ring included, the bearing runs directly on a hardened and ground shaft, which reduces radial section height while maintaining load capacity within its dimensional class. The standard cage design provides even roller spacing and stable guidance under radial load, supporting the speed ratings listed above.
