What is a combined bearing? What combinations are there?

2022-08-24

Due to the complex structure of many machines, multiple sets of bearings are required to be used in combination. 

A set of rolling bearings is a combination of two bearing structures at the same time. 

Such as needle roller and thrust cylindrical roller combined bearing, needle roller and thrust ball combined bearing, needle roller and angular contact ball combined bearing, etc.

Among them, the most widely used is the roller bearing.

Its unique design is a rolling bearing with short cylindrical, conical or drum-shaped rollers as rolling elements. Mainly used in the following fields: textile machinery, printing machinery, automobile industry, household appliances, money detectors.


Combination form of combined bearing

1. Needle roller and thrust ball combined bearing without inner ring

2. Needle roller without inner ring and thrust ball combined bearing with outer cover

3. Combination shaft with inner ring needle roller and thrust ball with outer cover

4. Needle roller and angular contact ball combination shaft

5. Needle roller and three-point contact ball combination bearing

6. Combined needle roller and thrust cylindrical roller bearing without inner ring

7. Combined needle roller bearing without inner ring and thrust cylindrical roller bearing with outer cover

8. Combination bearing with inner ring needle roller and thrust cylindrical roller

9. Combination bearing with inner ring needle roller and thrust cylindrical roller with outer cover

10. Needle roller and bidirectional thrust cylindrical roller combined bearing

11. Combined bearing with flanged needle roller and bidirectional thrust cylindrical roller
