Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can

sustain limited axial loads in one direction. Types NH and NUP can be used as fixed

end bearings. Loose rib for NUP inner ring should be mounted so that its marked side

faces outward.

If high load capacity is required, Series E cylindrical roller bearings, which have larger

rollers and more rollers than usual, are also available.

For standard cylindrical roller bearings, either pressed, machined or pintype cages

are used.
