This single row cylindrical roller bearing carries the internal geometry of type NJ, with two ribs on the outer ring and one rib on the inner ring, resulting in a semi-locating configuration that allows axial displacement in one direction while providing location in the other. Bore diameter is 45.0 mm, outside diameter 100.0 mm, width 36.0 mm, and net mass is 1.31 kg. The polyamide cage (TVP2) guides the rollers, and the E design provides increased load rating within the standard envelope. Limiting speed is 9800 1/min, reference speed 5200 1/min. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and load conditions without preload requirements. The semi-locating design allows the bearing to accommodate shaft thermal expansion in the free direction while still transmitting axial load in the fixed direction, making it suitable for shaft arrangements where one bearing position must remain free to move axially. As an open bearing without integrated sealing, relubrication access is unobstructed, and grease or oil lubrication can be applied according to the operating speed range indicated by the limiting and reference speed values.
