This cylindrical roller bearing carries axial displacement between shaft and housing, as its outer ring has two ribs while the inner ring is smooth, allowing free axial movement of the inner ring relative to the outer ring. It is a single row, caged design with bore diameter 140.0 mm, outside diameter 250.0 mm, and width 42.0 mm, weighing 9.02 kg. Limiting speed is rated at 4900.0 1/min, with a reference speed of 2600.0 1/min. The bearing is manufactured to running accuracy class P6 and radial internal clearance CN (Group N), with a solid brass cage designated M1. As a non-locating bearing type NU, it is suited for applications requiring compensation of axial shaft expansion without transmitting axial loads, while maintaining precise radial guidance under the specified accuracy class.
