This single row cylindrical roller bearing carries the designation NJ220-E-XL-M1-C3, with a bore diameter of 100.0 mm, outside diameter of 180.0 mm and width of 34.0 mm, weighing 3.88 kg. The outer ring has two ribs and the inner ring has one rib, type NJ, giving the bearing a semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. It runs with a limiting speed of 6800.0 1/min and a reference speed of 3450.0 1/min, fitted with an M1 cage of machined brass. The C3 radial internal clearance provides additional room to absorb thermal expansion and shaft fit tolerances, making the bearing suitable for applications where axial free movement on one side is required alongside radial load support. The E design denotes an optimized internal geometry for increased load carrying capacity, and the semi-locating arrangement permits the bearing to accommodate axial displacement of the shaft relative to the housing on the non-ribbed side.
