-
Since
the design allowing linear contact of cylindrical
rollers with the raceway provides strong
resistance to radial load, this type is suitable
for use under heavy radial load and impact load,
as well as at high speed.
-
N and
NU type are ideal for use on the free side: they
are movable in the shaft direction in response to
changes in bearing position relative to the shaft
or housing, which are caused by heat expansion of
the shaft or improper mounting.
-
NJ and
NF types can accommodate axial load in one
direction; and NH and NUP types can accommodate
partial axial load in both directions.
-
With
separable inner and outer ring, this type ensures
easy mounting.
-
Due to
their high rigidity, NNU and NN types are widely
used in machine tool spindles.
