This cylindrical roller bearing carries radial load through a single row of rollers guided by a solid brass cage (M1), with two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function. Bore diameter is 75.0 mm, outside diameter 160.0 mm, width 55.0 mm, and net mass 5.5 kg. The E design provides increased dynamic capacity, with a limiting speed of 7600.0 1/min and a reference speed of 3550.0 1/min. The inner ring can be displaced axially relative to the outer ring, so the bearing takes up shaft expansion while still providing guidance in one direction. Radial internal clearance C3 allows for tighter fits and thermal expansion under load, and the brass cage supports stable roller guidance at the stated speed range. Lubrication should be selected according to the actual operating speed and load conditions.
