This cylindrical roller bearing carries pure radial load and functions as a non-locating bearing, allowing free axial displacement between inner and outer rings. The single-row design features two ribs on the outer ring and a smooth inner ring (type NU), with bore 150.0 mm, outside diameter 320.0 mm, width 65.0 mm, and net mass 26.24 kg. Limiting speed is 3650 1/min, reference speed 1940 1/min. The E design provides increased load rating through optimized internal geometry, and the bearing runs to P6 accuracy class. The M1 cage, machined from brass, suits higher speeds and reduces friction losses, while C3 radial internal clearance compensates for thermal expansion during operation. The non-locating configuration accommodates shaft thermal growth and misalignment without inducing axial preload, making this bearing suitable for applications requiring axial freedom of the shaft combined with high radial load capacity and precise running accuracy.
