First, let's define what a shaft is: A shaft is defined as the component that links the main parts of a product and is used in rotational operations. It must be able to withstand both bending moments and torques. Such a shaft is called a "shaft".

Ball screw bearings can be applied in various production machinery, but they are most widely used in machine tools to achieve certain production purposes. During use, the circulation mode of the balls can be in the form of circulating conduits, circulators, or end caps. The existing pre-pressing methods mainly include positioning pre-pressing and constant pressure pre-pressing.

During use, it is necessary to make a proper selection of the type based on the purpose. Ball screws have this type with high-precision grinding processing, and their high precision has reached the six levels of CO-C7. There is also another type of ball screw bearing that is high-precision cold-rolled processing. The accuracy of this ball screw reaches the three levels from C7 to C10, and you can choose the ball screw that suits your needs from these levels.

Because the ball screw is in a continuous operating state during use, there will be considerable wear. Therefore, it is very important to pay attention to the lubrication of the screw when using it. To achieve a certain level of lubrication, lubricants need to be used. The lubricants commonly used on ball screws are mainly two types: one is lubricating oil, and the other is lubricating grease.

Lubricating oil can be made of engine oil, or 90-180 grade turbine oil. Some ball screw systems also use 140 grade spindle oil. For the lubricating grease used, lithium-based grease can be chosen. However, when using the grease, it should be added to the threaded raceway and the housing space of the installation nut.
