"The ball roller bearings" invention is based on the idea of a genius, it is the new rolling body and the new assembly method of the portfolio. All is not liable for load traditional roll "ball" spheres part been removed. This means that both sides of the ball diameter 15% be removed. The result is what is called a ball roller, a ball on both sides of the flat, than the real ball narrow 30%. This significant saving valuable space.

In addition, this shape "fine" ball of special roller and especially developed assembly method, can increase the number of roller, to about 90% of filling the space. In the same space in the rolling body can realize more higher rated load, so as to achieve a more long product service life. It also provides a new reduce product dimensions and assembly of the opportunity. Double maintains a design can realize two groove of the best independent adjustment, and complete match and application. This ensures the with minimum of the bearing size and more low friction for maximum load of support.

The rolling bearing in motion resistance to wear constantly because of bearing and failure, grease (oil) and the different ways of lubrication, the low bearing friction and wear different effect. So the lubrication technology has become the bearing an integral part of the study of technology. Someone put grease (oil) called "bearing the fifth part" (the other for inner ring and outer, rolling body, keep frame).

Hinder the resistance of the rolling bearing rotation by rolling friction, sliding friction and lubricant of friction. When rolling on the body will have the rolling friction; Sliding friction appeared in maintains a roll of the body surface, keep the frame of the guide roller bearing and raised edge on the guide of face and rings on raised edge roller. While the lubricant in lubricant friction of the contact point internal friction and lubricant mixing and squeezed together. A set of friction that is always bearing rolling friction, sliding friction and lubricant friction is the sum total of the resistance of the movement is impedance bearing. The task of lubrication technology research is to develop different (oil) and grease lubrication method, make its bearing the least resistance, the longest life expectancy.

 
To the common conditions bearing grease (oil), foreign advanced industrial countries in technology and production has been completely pass, has formed series varieties and batch production capacity, the main trend is research to improve some special circumstances grease characteristics, such as is research to improve the space with the grease of vacuum stability fluorine ether, climb and sticky temperature performance of move; And as low fat, although in the applications have better effect, but the lubrication mechanism fail to have a good theory in this paper. Be like again, study in high temperature (200 ~ 4000 degrees) use gas lubricant, etc.
