Combination needle roller bearing

The combination needle roller bearing is composed of radial needle roller bearing and thrust bearing. They can withstand both radial and axial loads simultaneously. In applications, when other types of positioning end bearing configurations occupy too much space, or the axial load is too heavy, the speed is too high, or the bearing configuration with simple thrust washers lacks lubrication, it is particularly suitable to use combination needle roller bearings. The provided combination needle roller bearings have the following basic designs:

Needle roller/angular contact ball bearing

Needle roller/thrust ball bearing

Needle roller/cylindrical roller thrust bearing

The supplementary lubrication interval for the radial and thrust components of the bearing must be calculated separately. The shorter interval between the two should be used as the standard.

Bearing characteristics:

Fixed bearing configuration

Carrying combined radial and axial loads in one or two directions.

Low cross-section

In applications that require less space, the combination of needle roller bearings provides a compact solution.

High carrying capacity

Due to the large number of rolling elements, the combination configuration of needle roller bearings has a high load-bearing capacity.
