This cylindrical roller bearing carries radial loads without axial constraint, functioning as a non-locating bearing that accommodates axial displacement between shaft and housing. It has a single row of rollers, a two-rib outer ring and a smooth inner ring, allowing the inner ring to move axially relative to the outer ring. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 51.0 mm, net mass 4.47 kg. Limiting speed reaches 8200 1/min, with a reference speed of 3800 1/min. The bearing is fitted with an M1A cage and features the E design for increased load carrying capacity. Radial internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without preload. Running accuracy corresponds to P6, offering tighter dimensional and running tolerances than standard class. As a non-locating bearing type NU, it is intended for mounting positions where axial float of the shaft must be permitted, such as the floating bearing position in a shaft arrangement with two supports.
