FAG NJ228-E-XL-M1 - Cylindrical roller bearing NJ..-E-XL-M1, with cage, single row, semi-locating bearing, 2 ribs on outer ring, 1 rib on inner ring, type NJ.
NJ228-E-XL-M1 FAG have high rigidity, high radial load-carrying capacity and, due to the cage, are suitable for higher speeds than full-complement designs. NJ228-E-XL-M1 bearings with suffix E have a larger roller set and are thus designed for extremely high load-carrying capacity.
NJ228-E-XL-M1 FAG have two rigid ribs on the inner ring and one rigid rib on the inner ring. In NJ228-E-XL-M1 FAG bearings, axial displacements of the shaft relative to the housing are possible in one direction only.NJ228-E-XL-M1 bearings are used as semi-locating bearings, they can guide the shaft axially in one direction.
