Spherical roller bearings have noise causes?

At present, Chinas self-aligning roller bearings and foreign advanced products within the companys internal structure parameters are almost the same, but our products such as vibration and noise levels with foreign products is very different, mainly due to manufacturing and operating conditions factors. From the bearing industry point of view, the operating conditions of the host can make reasonable demands to solve, and how to reduce the vibration caused by manufacturing factors and noise is the bearing industry must solve the problem. Spherical roller bearings caused by noise in the end what factors are, the following is for everyone to sum up, I hope you can help Oh!
1. Choose a variety of lubricants or grease caused by self-aligning roller bearing noise;
2. Lack of lubrication (oil level is too low, oil or grease leakage through the seal);
3. Spherical roller bearing clearance is too small (with the choice of inappropriate);
4. Spherical roller bearings mixed with sand or carbon particles and other impurities, play the role of abrasive;
5. Spherical roller bearings mixed with water, acid or paint and other dirt, play a corrosive effect;
6. Self-aligning roller bearing is flattened by seat hole (seat hole roundness is not good, or seat hole distortion is not straight);
7. Self-aligning roller bearing seat of the bottom of the horns uneven (resulting in seat hole deformation even spherical roller bearing seat cracks);
8. Spherical roller bearing seat with debris (residual chips, dust, etc.);
9. Eccentric ring caused by self-aligning roller bearing noise (touch the adjacent parts and friction);
10. Spherical roller bearings subject to additional load (self-aligning roller bearing by axial tight, or an axis with two fixed-end spherical roller bearings);
11. Spherical roller bearings with the shaft is too loose (the diameter of the shaft is too small or tight set of not tightened);
12. Self-aligning roller bearing clearance is too small, too tight rotation (tight set of tightening too far);
13. Self-aligning roller bearing noise (roller end or ball skid caused);
14. Shaft thermal expansion is too large (self-aligning roller bearing by the static variable axial additional load);
15. Shoulder is too large to cause self-aligning roller bearing noise (encounter self-aligning roller bearing seals and friction).
