This single row cylindrical roller bearing carries the designation NJ219-E-XL-M1-C3, with a bore of 95.0 mm, outside diameter of 170.0 mm, and width of 32.0 mm. The design features two ribs on the outer ring and one rib on the inner ring, type NJ, giving a semi-locating function that allows axial displacement of the non-ribbed ring relative to the roller and cage assembly. Net mass is 3.23 kg, limiting speed is 7200 1/min, and reference speed is 3650 1/min. The bearing uses an M1 machined brass cage and the E design roller set for increased load carrying capacity. Radial internal clearance is C3, wider than standard, which compensates for thermal expansion under operating conditions and interference fits. The semi-locating configuration permits axial movement of the shaft relative to the housing while still providing radial guidance, making the bearing suitable for arrangements where the shaft needs freedom to expand axially. As an open bearing without integrated seals, lubrication and sealing must be provided externally, and mounting should follow standard practice for cylindrical roller bearings with separable rings.
