In our life every day for at least 200 bearing, it has changed our life, scientists are now given bearing a wisdom of the brain, let it have ideas will talk.
In the high-speed precision bearing, people can do it without repair can understand all bearing.
With the rapid development of science and technology, bearing pressure became more and more powerful, the quality requirements will be higher.
The concept and classification of common rolling bearing rolling bearings generally consists of two ring (
The inner ring and outer ring)
Basic element, rolling element and cage.
In order to apply to the use of some special requirements, some parts of the some bearing can increase or decrease.
Four big functions 1 rolling bearing, the inner ring and the shaft is usually tight fit, and with the axis rotation.
2, outer ring and bearing seat usually holes or cooperate with mechanical parts of shell, the supporting role.
3, using roller cage homogeneous permutation, and between the outer ring, its practice, bearing capacity depends on the size and quantity directly.
4, cage will be evenly separated, roller guide roller in the right orbit.
