(1) The bearing of the vibratory separator used in China
Bearing，as the bearing of the vibratory separator is the key component of the vibratory separator. The first thing to consider is how strong the radial load resistance is. Nowaday, the selection of the bearing of the vibratory separator in China is also very inconsistent for the changeable load， which includes cylindrical roller bearings and self-aligning roller bearings. Moreover, they have both merits and demerits.
Self-aligning roller bearings: under the condition of large bending drive shaft and hardly concentric guarantee as well as variable load, it has an absolute advantage. But for the low limit speed of the bearing itself and the large noises , it is not suitable for the high-frequency screen. Cylindrical roller bearings: With high limit speed, smooth operation , low noise, high requirements for concentricity installation, while with the gradual improvement of processing means and precision of coal preparation equipment, cylindrical roller bearings gradually win the trust of more vibrating screen manufacturers. （2）Vibrating screen bearing used outside China
For the bad working environment of the vibratory separator, special bearings for vibration machinery has been used in countries, especially some developed countries, such as: the United States, Japan and etc. Special bearings for vibration machinery have always affected the development of vibration machinery. Compared with ordinary bearings, special bearings for vibration machinery have the following characteristics:
(1) The design of special bearing for structural vibration machinery takes full account of the use characteristics under vibration working conditions.
In the design, the roller with increased diameter and length is selected, and the outer contour of the roller has a special shape modification design, which improves the edge stress caused by deviant load. The bearing cage adopts the guide integral structure, which completely changes the traditional roller guide mode, to reduce the force of the cage and improve the lubrication effect. The manufacturing precision is strictly according to the standard of P6 precision, the size difference of the roller is less than 0.002, the surface of the roller is superfine, and the surface roughness is high. Therefore, the bearing capacity of special bearing for vibration machinery is about 25% higher than that of ordinary standard bearings for the same specifications and models of bearings (that is, when the outer diameter and inner diameter of the bearing are the same). When calculating the bearing life, the load factor can be reduced from 1.8~2.5 to 1.2~1.5. In this way, the special bearing for vibration machinery is lower than the ordinary standard bearing.
