This cylindrical roller bearing carries pure radial load through a single row of rollers guided by a machined cage (M1), with two ribs on the outer ring and a smooth inner ring, allowing the inner ring to displace axially relative to the outer ring — a non-locating bearing design. Bore is 150.0 mm, outside diameter 270.0 mm, width 73.0 mm, net mass 18.04 kg. Limiting speed is 4550 1/min, reference speed 1850 1/min. The E design provides increased load rating compared to standard internal geometry. Radial internal clearance is CN (Group N), suited for standard fit conditions without preload requirements. Running accuracy is manufactured to P6, giving tighter dimensional and rotational tolerances than standard P0 class. As a non-locating bearing, it accommodates axial displacement of the shaft caused by thermal expansion or load-induced deflection, while the smooth inner ring allows free axial sliding of the rollers along the raceway.
