NX type combined needle roller bearings
Needle roller bearings with angular contact ball bearing is
combinations of a radial bearing and a thrust bearing.
Caged needle roller bearings are 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.
Needle roller bearings with angular contact ball bearing is widely
used for machine tools, textile machinery, and industrial
machinery.
Needle Roller Bearings with Angular Contact Ball Bearing
In this series, caged needle roller bearings are combined with
angular contact ball bearings to receive thrust loads. These needle
roller bearings with angular contact ball bearings conform to the
international dimension series #59, which is based on the ISO
Standard. They can withstand heavy radial loads and unidirectional
axial loads simultaneously.
When the axial load exceeds 25% of the radial load, the radial load
will be induced in the angular contact ball bearing, and bearing
life will be affected. The relationship between the two loads must
therefore be taken into careful consideration.

Notes
(1) Minimum allowable value of chamfer dimension r
(2) Allowable rotational speed applies to oil lubrication. For
grease lubrication, a maximum of 60% of this value is allowable.
Remarks
1. The outer ring has an oil groove and an oil hole.
2. Grease is not prepacked. Perform proper lubrication.
