of R&Z cylindrical roller bearing: Available in various
designsHigh to very high load ratingsAvailable with cylindrical or
tapered boreDouble row cylindrical roller bearings with cage can
absorb very high radial forces due to the linear contact between
rolling element and bearing ring. They are classified into two
general designs which differ in flange position on the inner or
outer ring. Double row cylindrical roller bearings can be
disassembled and are easily installed or uninstalled. They are
suitable for medium to high speeds, but they are rigid and cannot
compensate angular misalignments. N type:The inner
ring has two integral flanges and the outer ring is without
flanges. Axial displacement of the shaft with respect to the
housing can be accommodated in both directions within the bearing
itself. The bearings are therefore used as non-locating bearings.NU
type:The outer ring of bearings of the NU design has two integral
flanges and the inner ring is without flanges. Axial displacement
of the shaft with respect to the housing can be accommodated in
both directions within the bearing itself.NJ type:The outer ring
has two integral flanges and the inner ring one integral flange.
The bearings are therefore suitable for the axial location of a
shaft in one direction.NF type:The outer ring has one integral
flange and the inner ring two integral flanges.NUP type:The outer
ring has two integral flanges and the inner ring one integral
flange and one non-integral flange in the form of a loose flange
ring. The bearings can be used as locating bearings, i.e. they can
provide axial location for a shaft in both directions.RN type:No
outer ring and the inner ring two integral flanges.NN type:NN type
bearing without ribs on outer ring,there is a wall in the midel of
between both sides of inner ring. It can make shaftrelative bearing
between the axial displacement generated in both
directions.ApplicationLarge motors, Machine tool spindles, Engine
