This cylindrical roller bearing carries radial loads at a bore diameter of 140.0 mm, outside diameter of 250.0 mm and width of 42.0 mm, weighing 9.5 kg. It is a single row design with two ribs on the outer ring, one rib on the inner ring, and a loose rib washer, functioning as a locating bearing. The cage is a machined brass cage (M1), and the E design provides increased load rating compared to standard internal geometry. Limiting speed is 4900 1/min, with a reference speed of 2600 1/min. The C3 radial internal clearance accommodates thermal expansion and shaft fit conditions requiring greater clearance than standard. The locating function of the NUP configuration allows the bearing to carry axial loads in one direction while permitting free axial displacement of the shaft in the opposite direction, making it suitable for fixed-bearing positions where one-directional axial guidance combined with radial load capacity is required. The machined brass cage supports operation at the stated speed ratings.
