Introduction to the fixing method of the inner ring of imported bearings

Imported bearings are divided into inner and outer rings. I think everyone knows this. So what is the fixing method of the inner and outer rings of the imported bearing? First, let’s introduce the fixing method of the inner ring of the imported bearing.

1. Fixed shoulder

The inner ring of the bearing is axially fixed by the shoulder and interference.

Suitable for supporting structures fixed at both ends.

The structure is simple and the outline size is small.

2. The circlip is fixed

The inner ring of the bearing is axially fixed by the shaft shoulder and the lock nut.

It can bear small bidirectional axial load.

The axial structure size is small.

3. Lock nut to fix

The inner ring of the bearing is axially fixed by the shaft shoulder and the lock nut. And there is a stop washer to prevent loosening, reliable, suitable for high-speed, heavy-duty occasions.

4. End face thrust washer fixed

The inner ring of the bearing is axially fixed by the shaft shoulder and the shaft end retaining ring. The shaft end retaining ring is fixed on the shaft end with screws. The fixing screws should have anti-loosening devices.

It is suitable for occasions where the shaft end is not suitable for thread cutting or the space is restricted.

5. Adapter sleeve fixed

Relying on the radial size of the inner hole of the adapter sleeve being compressed and clamped on the shaft, the axial fixation of the bearing inner ring is realized.

6. Withdrawal sleeve fixed

The clamping method of the withdrawal sleeve is the same as that of the adapter sleeve. However, because the withdrawal sleeve has a special nut, the bearing is easy to load and unload, and it is suitable for fixing the double row spherical bearing with large radial load and small axial load on the optical axis.
