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
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
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
