How to prolong the service life of rolling bearings

In the actual production of which, machinery and equipment used by the fixed bearing life is directly related to the length of the normal use of mechanical equipment and normal production. Although according to different environments and conditions selected bearings, but there are many in the far reaches of the bearing design life when it is damaged and ineffective. Failure of a bearing used in the production of which will produce severe vibration and noise, but also make the damaged parts, the final result set of adverse effects. Bearing failure modes are the following, fatigue pitting, excessive permanent deformation and wear, glue, inside and outside the ring fracture, rolling crush, break the cage wear, mostly beads frame damage, beads away, outside won badly worn.
In addition, the inner ring fracture, because the bearing to withstand the same load, the contact area between the inner roller moral large than the outer roller, the contact point, the inner raceway withstand large pressure than the outer race, will cause inner ring begins to fail. Therefore, the study of the failure of the inner ring and find the appropriate solution is an effective way to extend the life of rolling Cylindrical roller bearing  Also, the study bearing noise, torque, runout, pollution prevention, thermal expansion and other issues are also related to the state of West bearing life is an important factor.
One of the reasons causing premature bearing failure
Cause premature bearing failure for many reasons, but the main thing is to use and improper maintenance and improper lubrication, poor lubrication, contamination overload, assembly, transportation, demolition occurred during impact and shock. Pollution is caused by man, because no sperm clean removal tool and other factors.
Pitting is the most typical form of bearing failure, mainly because of the bearing frequent impacts during transportation and incorrect assembly, make raceway indentation. When the raceway after indentation. The rotating roller, each indentation is produced after a first impact, on a rolling indentation effect, when the load increases, the greater the pressure roller in the cycle of movement which, at the indentation will produce flakes peeling, and to increase the vibration, noise increases.
