Selection and notes of hybrid ceramic ball bearings

Currently, the most widely used high-speed spindle bearings is hybrid ceramic ball bearings, which use rolling or hot isostatic pressing Si3N4 ceramic ball bearing ring remains rims. This bearing high standardization, low price, small changes in the machine tool, easy maintain, high-speed operation suitable for occasions. It's d · n values over 2.7 × 106. In order to increase bearing life, increase the wear resistance of roller on the roller for coating or other surface treatment.
     Select bearing and not necessarily in the order, rules, priority consideration should be to the conditions required by the bearing, performance, the most relevant issues, especially the practical.

     Rolling is the precision components, their use has to be carefully carried out accordingly. Regardless of how high-performance bearings, if used improperly, it will not get the expected performance. Use of the bearings as follows.
a. maintain the bearing and the surrounding clean.
Even the eyes can not see the small dust, will bring bad effect to the bearings. So, to keep the surrounding clean, so dust will not invade bearings.
b. careful use.
Bearing in use to give a strong impact, will have scars and indentations, a cause of the accident. Severe cases, cracks, fracture, it should be noted.
c. use appropriate operational tools.
To replace existing tools to prevent, you must use the appropriate tool.
d. Bearing in mind the rust.
Bearing operation, the hand will be rusty because Khan. Note operation with clean hands, the best possible wear gloves.
For as long as possible in order to maintain good condition bearing the original performance, to maintenance, overhaul, in order to prevent accidents in the first place, to ensure reliability of operation, increase productivity, economy.
