Some have been lubricated bearing itself, called pre-lubricated bearings Needle roller bearings F1712, while most of the bearing lubricant, or in high-speed operation, due to the friction will not only increase consumption of needle roller bearings F1718, even more frightening is very easy to damage the bearing, such as motor bearing no consequences is simply not working. Because the axis may be in any direction movement, the motor work requirements shaft can only be rotated.
