This cylindrical roller bearing carries radial loads through a single row of rollers guided by a machined cage designated M1. The design features two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function that allows axial displacement in one direction while the flanges retain the roller set on the other side. Bore diameter is 30.0 mm, outside diameter 72.0 mm, and width 19.0 mm, with a net mass of 0.274 kg. Limiting speed reaches 18500 1/min, reference speed 8900 1/min. The internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without preload. The E design of the cage and roller set supports increased load capacity within the same envelope dimensions compared to standard internal geometry. The semi-locating configuration makes this bearing suitable for shaft arrangements where axial movement must be accommodated at one bearing position while radial guidance is maintained, and the machined cage supports stable roller guidance at the given speed range.
