This cylindrical roller bearing has a bore diameter of 120.0 mm, outside diameter of 260.0 mm, and width of 55.0 mm, with a net mass of 15.321 kg. It is a single row, non-locating design of type NU, featuring two ribs on the outer ring and a smooth inner ring, which allows axial displacement between the rings. The bearing uses an M1 cage and is built to the E design for increased load carrying capacity. Running accuracy is held to P6, with radial internal clearance in the CN (Group N) range. Limiting speed is 4550.0 1/min, with a reference speed of 2650.0 1/min. The non-locating configuration and smooth inner ring allow the bearing to accommodate axial movement of the shaft relative to the housing, making it suitable as a floating bearing position where thermal expansion or shaft length changes must be compensated. The P6 running accuracy supports precise radial guidance, while the CN internal clearance provides a standard operating fit for typical radial load conditions. The M1 cage design and E construction support stable roller guidance and load distribution at the given speed and load ratings.
