High Precision Ball Bearings 6802ZZ

Ball bearings are belong to one of rollings bearings which are widely used in life, they are characterized by simple structure, low friction resistance, high speed and  easy to use etcs, they can be used for applications that support moderate radial load or both moderate radial and axial load at the same time, and also for moderate  axial load.they can operate at very high speeds for some special applications such as dental turbine,the speed can be RPM400000 or even more. The parts of ball bearings include inner ring,outer ring,retainer,balls,grease,shields or rubber seals. Compared with other type of rolling bearings, ball bearings are simple in structure and easy to achieve higher manufacturing accuracy, with a low manufacturing costs, so they are easy to be produced in large quantities and widely used. The rotational friction resistance of ball bearing is much smaller than other kinds of bearings, so the temperature generated by friction will be relatively low at the same speed. Therefore, ball bearing are widely used in high-speed equipment。There are open type, with shields or rubber seals for ball bearing.Usually ball bearings are also called deep groove ball bearings.

High precision ball bearings is referred ball bearings with a very high precision, Zhangzhou Runstar Bearings Manufacturing Co.;Ltd is the leader of high precision ball bearings in China,we specilize in designing and manufactuing high precision ball bearings from ABEC-1 to ABEC-9 for industries,the material could be chrome steel,stainless steel or hybrid ceramic balls for choices.
