FAG NU248-E-M1-C3 - Cylindrical roller bearing NU..-E-M1, with cage, single row, non-locating bearing, 2 ribs on outer ring, 0 ribs on inner ring (smooth), type NU, Running accuracy in P6.
NU248-E-M1-C3 FAG have high rigidity, high radial load-carrying capacity and, due to the cage, are suitable for higher speeds than full-complement designs.
NU248-E-M1-C3 FAG have two rigid ribs on the outer ring, and have no ribs on the inner ring. As a result, axial displacements of the shaft relative to the housing are possible in both directions and within certain limits. During rotational motion, length compensation occurs without constraint in the bearing between the rollers and the raceway without ribs and is therefore practically free from friction. NU248-E-M1-C3 bearings are used as non-locating bearings - they cannot guide the shaft axially in either direction.
