NKX TYPE Combined Needle Roller Bearings
Needle roller bearings with thrust roller bearing is combinations
of a radial bearing and a thrust bearing.
Needle roller bearings with thrust roller bearing is used as radial
bearings and thrust ball bearings or thrust roller bearings are
used as thrust bearings. They are compact and very economical, and
can be subjected to radial loads and axial loads simultaneously.
They are widely used for machine tools, textile machinery, and
industrial machinery.
Needle Roller Bearings with Thrust Roller Bearing
In this series, needle roller bearings are combined with thrust
roller bearings to receive thrust loads.
Their axial load ratings are greater than those of bearings that
are combined with thrust ball bearings. Also, elastic deformation
of the rolling contact surfaces under load is minimal. Furthermore,
the thrust bearing section is finished to high accuracy, and
therefore high rotational accuracy is obtained in the case of both
vertical and horizontal shafts.
Like the needle roller bearings with thrust ball bearing, this
series also includes bearings with a dust cover and bearings with
an inner ring.
