4.  Series of  cylindrical roller bearing

a. Types NU, N, NNU, and NN are suitable as free-end bearings. 

b. Types NJ and NF can sustain limited axial loads in one direction.

c. Types NH and NUP can be used as fixed-end bearings.

d. NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-               shaped thrust collars.

e. The inner ring loose rib of an NUPtype cylindrical roller bearing should be mounted so that the marked       side is on the outside.

f. The RNU cylindrical roller bearing has an outer ring with double capped edges but does not come with       inner ring. Such bearing is the NU cylindrical roller bearings without the inner ring 

g. The RN cylindrical roller bearing has an inner ring with double capped edge but does not come with           outer ring.
