This needle roller bearing has a solid inner ring, giving it full radial section height and higher load capacity for its size compared to designs without an inner ring. Bore diameter is 28.0 mm, outside diameter 42.0 mm, and width 20.0 mm, with a net mass of 91.412 g. The limiting speed is 14000 1/min and the reference speed 7500 1/min, with a machined cage (TV) guiding the needle rollers. Radial internal clearance is in the CN (Group N) range, suitable for standard mounting conditions without additional preload requirements. The solid inner ring allows direct mounting on the shaft without a separate inner raceway component, simplifying installation while maintaining running accuracy. As an open bearing without integrated sealing, it requires external protection of the mounting environment and separate lubrication, typically with grease or oil, matched to the operating speed and temperature range.
