Using the factor mainly refers to the installation and adjustment, maintenance, maintenance repair and other compliance with technical requirements. According to the requirement of outer sphere spherical bearing installation, use, maintenance, maintenance technology, the bear to the outer spherical ball bearing in the operation of the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons, adjustment, restore normal. Installation conditions is one of the leading factors in the use factor, the bearing is often caused by the installation of inappropriate stress state between the various parts of the complete bearing change, bearing an abnormal state operation and early ending life of internal factors mainly refers to the three major factors for structure design, manufacturing process and material quality determine the bearing the quality of the.
The metallurgical quality of bearing materials is the main factor affecting the early failure of rolling bearings once. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors has been a marked decline in the proportion of bearing failure analysis, but it is still one of the main factors of bearing failure. Proper selection is still bearing failure analysis must be considered.
Manufacture of bearings are generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced, stability of the machining process can also affect the outer spherical ball bearing life. The effect of heat treatment and grinding process quality of finished bearings, often has a more direct relationship with the bearing failure. Study on bearing surface modification layer of work in recent years, the relationship between grinding and surface quality of bearing close.

The main task of the service life of the bearing, is based on the analysis of data and failure forms of the large amount of background material,, identify the main factors causing bearing failure, so as to put forward the improvement measures, extending the service period of bearings, avoid unexpected early bearing failure.
(1), keep the bearings and the working environment clean.
Even if is the eye cannot see small dust, will bring bad effect to the outer spherical ball bearing. So, to keep the surrounding clean, so that dust is not into the bearing.
(2) use, circumspect.
And bearing a strong impact in use, will have scars and indentation, became the cause of the accident. In severe cases, will crack, fracture, so be careful.
(3), using the right tools.
To avoid the existing tools instead, you must use the appropriate tool.
(4), pay attention to corrosion of bearings.
Operation spherical ball bearing, hand Khan will become the cause of rust. To note that the clean hands operation, the best to wear gloves.
