At present, the application of the most high speed spindle bearing or mixed ceramic ball bearings, namely rolling body use hot pressing or hot isostatic pressing Si3N4 ceramics ball, bearing collar is still rims. This bearing standardization degree is high, the price is low, changes of machine is small, easy maintenance, especially suitable for high speed running occasion. Its d. n value already more than 2.7 by 106. In order to increase the service life of the bearings, can increase the wear resistance of rolling way, way to roll on coating processing or other surface treatment.

Choose bearing and no certain order, rules, priority should be considered for bearing is required conditions, performance, most associated issues, particularly the actual.

The rolling bearing is precision components, its use has to be carefully accordingly. No matter how high performance bearing use, if use undeserved, it won't get the expected performance. The bearings use of the note as follows.

A. keep around the bearing and clean.

Even the small dust eyes see, also can give bearing bring bad influence. So, to keep clean around, make dust from invading bearing.

B. careful to use.

In use give bearing strong impact, will produce the scars and impress, become the cause of the accident. Severe cases, will crack, fracture, so must pay attention to.

C. Use proper operating tools.

Avoid to existing tools instead of, must use appropriate tools.

D. to note bearing the corrosion.

Operation bearing, hands sweat will be the cause of rust. To pay attention to use clean hand operation, better try to bring gloves.
For as long as possible with good performance of the original state maintain bearing, shall be the maintenance, the maintenance, in order to prevent accident cure, ensure reliability of operation, improve productive and economy.
