A set of bearings at the same time there are two bearing structure form combination of rolling bearings. Such as needle roller and thrust cylindrical roller combination bearings, needle roller and thrust ball combination bearings, needle roller and angular contact ball combination bearings, etc.
1. no inner ring needle roller and thrust ball combination bearings 2. no inner ring needle roller and thrust ball combination bearings with outer cover
3. needle roller bearings with inner ring and thrust ball bearings with outer cover
4. needle roller and angular contact ball bearings
5. Needle roller and three-point contact ball bearings
6. needle roller and thrust cylindrical roller combination bearings without inner ring
7. needle roller bearings without inner ring and thrust cylindrical roller bearings with outer cover
8. Combined needle roller and thrust cylindrical roller bearings with inner ring
9. inner ring needle roller and thrust cylindrical roller bearings with outer cover combination
10.Needle roller and two-way thrust cylindrical roller combination bearings
11.Combined needle roller and two-way thrust cylindrical roller bearings with flange
1.Combined bearing internal clearance is too small
2.Excessive load
3.Excessive friction of sealing device
4.Lubricant does not match
5. Creep of the mating surface
To determine whether the bearing can be used again, we should consider the level of damage to the combination bearing, mechanical function, primacy, operating conditions, search cycle, etc. and then choose. The new bearing can be replaced by careful inspection of the new bearing, while the shaft diameter and bearing seat hole and rotor for careful inspection and assembly and disassembly of the bearing, strict implementation of the maintenance process, careful operation, to avoid improper installation and disassembly of the bearing damage and oil change on time, to ensure that the working condition of the bearing is always in good condition; in the operation of the combination of bearings carefully checked, found fault hidden, timely elimination In the operation of the combination bearing, we will check carefully, find the hidden trouble and eliminate it in time.
