Cylindrical Roller Bearings Bore Diameter 100 – 850mm

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

rollers and more rollers than usual, are also available.

are used.
