Combined Needle Roller Bearings/50*110*82mm/NKIA/NKIB/NX/NKX/NKXR/NKXRZ/ZARN/ Z..ARF
The combined needle roller bearings can bear radial loads or intermediate uniaxial axial loads through dense needles.
You can make the space between the axes very small.The minimum center size is the outer ring size of the bearing.
Introduction to composite bearings:
Several combinations of bearings
1. Combination bearing with needle roller and thrust ball without inner ring
2. Combination bearing without inner ring needle and thrust ball with outer cover
3. Combination bearing with inner ring roller needle and thrust ball with outer cover
4. Needle and angular contact ball combination bearing
5. Combination bearing with needle roller and three-point contact ball
6. Combination bearing without inner ring needle and thrust cylindrical roller
7. Combination bearing with needle without inner ring and cylindrical roller with outer cover
8. Inner ring needle roller and thrust cylindrical roller combination bearing
9. Combination bearing with inner ring needle and cylindrical roller with outer cover
10. Combination bearings with needle roller and two-way thrust cylindrical roller
11. Cylindrical roller combination bearing with flanged needle and two-way thrust
Combined Type Needle Roller Bearings are 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. They are widely used for machine tools, textile machinery, and industrial machinery.
Combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing and are consequently able to take up both radial and axial loads. Combined needle roller bearings provide the means to produce locating bearing arrangements in a minimum of radial space. They are particularly useful where the axial loads are too heavy, speeds too high, or lubrication inadequate for simple thrust washers to be suitable, and other types of locating bearing take up too much room.
