This needle roller bearing carries a single row of rollers without an inner ring, giving an outside diameter of 30.0 mm and a width of 13.0 mm at a net mass of 23.27 g. Lip seals are fitted on both sides (2RSR), sealing the raceway against contamination while retaining lubricant inside the bearing. The limiting speed is rated at 12000 1/min, and the cage is of standard design. The double-sided lip seal arrangement allows the bearing to operate without additional external sealing, keeping the internal grease fill protected from ingress of dust and moisture. Its compact radial section combined with a full complement of needle rollers provides high radial load capacity relative to its outside diameter, suiting applications where mounting space is limited and a shaft with a hardened, ground raceway surface is available.
