Usually, during the installation process, simply use a wrench to move clockwise. When disassembling, it can be removed by turning it counterclockwise. Different specifications and lengths of screws can be selected based on different contours, groove widths, and installation requirements. Screw can be widely used in some industrial production and mechanical processing production. In industrial and mining enterprises, screws are often seen. Even if it is small, its effect is infinite. It is widely used in our lives. There are many differences in the material of screws, and correspondingly, screws of different materials are used in different scenes and positions.

Based on years of accumulated product technology, screw bearings are managed with a rigorous quality assurance system from materials, heat treatment, manufacturing, inspection to shipment. Therefore, they have high reliability. So, what are the applications of screw bearings?

1. Nut rotating (R1) series lead screws: semiconductor machinery, industrial robots, woodworking machines, laser processing machines, conveying devices, etc;

2. Rolling grade screw: The advantages of low friction and smooth operation, as well as fast supply and low price;

3. Heavy load screw: all electric injection molding machines, stamping machines, semiconductor manufacturing devices, heavy-duty brakes, industrial machinery, forging machinery.

When the screw is running, the temperature rise will affect the accuracy of the mechanical transmission system, mainly for high-speed and precise machinery. The factors that affect the temperature rise of the screw are the following three:

1. The impact of preloading.

To avoid errors in the mechanical transmission system, it is important to increase the rigidity of the nut. However, to increase the rigidity of the nut, it is necessary to ensure that the pre pressure of the nut reaches the corresponding level. Applying preload to the nut will increase the frictional torque of the screw teeth and increase the temperature rise during operation.

2. The impact of lubrication.

The selection of lubricating oil directly affects the temperature rise of the screw.

3. The impact of pre tensioning.

When the temperature of the screw rises, the thermal stress effect will cause the screw to elongate, making the length of the screw unstable
