This single row cylindrical roller bearing NJ218-E-XL-M1 has a bore of 90.0 mm, outside diameter of 160.0 mm and width of 30.0 mm, with a net mass of 2.65 kg. The design features two ribs on the outer ring and one rib on the inner ring, making it a semi-locating bearing that allows axial displacement of the ring without the rib in one direction while providing axial guidance in the other. The E design indicates an optimized internal geometry for increased load carrying capacity. The cage is machined brass, type M1. Limiting speed is rated at 7800 1/min, with a reference speed of 3900 1/min. Radial internal clearance corresponds to CN (Group N), the normal clearance group. The semi-locating function allows this bearing to accommodate axial shaft expansion while still transmitting axial loads in one direction, which is useful where a fixed-floating bearing arrangement is required on one side of the shaft. The brass cage construction suits operation at the stated speed levels and supports stable roller guidance under radial load. Normal internal clearance (CN) makes the bearing suitable for standard fit conditions without additional preload requirements, and the separable inner ring simplifies mounting and dismounting during assembly.
