Combined bearings NKIA and NKIB have an inner ring
NKIB has one narrow inner ring and one wide inner ring. The axial
bearing component has a plastic ball cage. At the point where the
inner rings join, there is a shoulder on both sides for guidance of
the ball and cage assembly.
Lubrication :
NKIA and NKIB can be lubricated with grease or oil. For
lubrication, the outer ring has a lubrication groove and
lubrication hole.
Operating temperature :
They are suitable for operating temperatures from –20 °C to +120
°C.
Cages :
The radial cages are made from sheet steel or plastic. Bearings
with a plastic cage have the suffix TV.

FAQ
What is the application of combined needle roller bearings?
Combined needle roller bearings are used for two purposes; for
applications requiring high accuracy and combined transmission of
large radial and axial forces. Combined type needle roller bearings
are combinations of a radial bearing and a thrust bearing.
What is combined needle roller bearings?
Combined needle roller bearings consist of a radial needle roller
bearing combined with a thrust bearing. They can accommodate both
radial and axial loads. They are particularly suitable for
applications where other types of locating bearing arrangements
occupy too much space, or where the axial loads are too heavy, the
speeds are too high, or the lubricant is inadequate for
arrangements with simple thrust washers.
