This single-row cylindrical roller bearing (NJ318-E-XL-TVP2) has a bore of 90.0 mm, an outside diameter of 190.0 mm, and a width of 43.0 mm, with a net mass of 5.4 kg. The design follows type NJ, with two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function that allows axial displacement of the non-ribbed side while the ribbed side provides axial guidance in one direction. The bearing uses a TVP2 polyamide cage and features the E design for increased load carrying capacity. Limiting speed is rated at 4900 1/min, with a reference speed of 3650 1/min. The radial internal clearance is CN (Group N), suitable for standard fit and operating conditions without special preload requirements. The semi-locating configuration allows the bearing to accommodate axial displacement caused by thermal expansion of the shaft, while still providing radial support and directional axial guidance. The cylindrical roller design ensures high radial load capacity, and the E variant increases the number and size of the rollers for improved load distribution. This bearing is suited for applications where axial float on one side is needed alongside precise radial positioning.
