This needle roller bearing carries a solid inner ring, giving it a compact radial cross-section for its load capacity. Bore diameter is 38.0 mm, outside diameter 53.0 mm, and width 20.0 mm, with a net mass of 0.135 kg. The limiting speed is rated at 10700 1/min, while the reference speed is 6000 1/min. The cage is of standard design, guiding the needle rollers evenly around the raceway. The solid inner ring construction allows this bearing to handle radial loads with high rigidity in a limited installation space, making it suitable where a compact radial dimension combined with a solid inner ring is required. As it is supplied without integrated seals, external sealing and a separate lubrication supply must be provided by the housing design. The standard cage ensures consistent roller spacing under the specified speed range, and the bearing should be fitted with an adjacent bearing capable of taking up axial loads, since this type is designed for radial load support only.
