Combined needle roller bearings
SKF 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. SKF supplies combined needle roller bearings in the following basic designs:
Relubrication intervals for the radial and thrust part of the bearing must be calculated separately. The shorter of the two intervals should be used. For additional information about lubrication, refer to Lubrication.
Locating bearing arrangement
Accommodate combined radial and axial loads in one or both directions.
Low cross section
In applications where less space is available, combined needle roller bearings offer a very compact solution.
High carrying capacity
Owing to their large number of rolling elements, combined needle roller bearings have a high load carrying capacity.
