This cylindrical roller bearing is a single-row, non-locating design with a solid brass cage (M1) guiding the rollers, rated for a bore of 80.0 mm, outside diameter of 125.0 mm and width of 22.0 mm, with a net mass of 0.96 kg. The outer ring carries two ribs while the inner ring is smooth (no ribs), which is the geometry of type NU and allows axial displacement between inner and outer ring to compensate for shaft expansion. Radial internal clearance is CN (Group N), running accuracy is manufactured to P6, limiting speed reaches 10800 1/min and reference speed is 5000 1/min. Because the inner ring runs smooth against the rollers, this bearing only transmits radial load and must be paired with a locating bearing on the opposite side of the shaft to take up axial forces. The P6 running accuracy and CN clearance make it suitable for applications requiring tighter shaft guidance and higher rotational precision than standard tolerance bearings, while the brass cage supports operation at the stated limiting and reference speeds.
