The use of bushings is more flexible, it can play a lot of role, generally speaking, bushing is a kind of component to protect the equipment. The use of bushings can reduce wear, vibration and noise of the equipment, and has anti-corrosion effect.
The use of bushings can also facilitate the maintenance of machinery and equipment, simplify the structure of equipment and manufacturing processes. The role played by the bushing in practical work is closely related to its application environment and purpose. In the field of valve application, the bushing is installed in the valve cover to hold the stem, in order to reduce the leakage of the valve, to achieve sealing effect. In the field of bearing applications, the use of bushings can reduce the wear between the bearing and the shaft seat, and avoid the increase of the gap between the shaft and the hole.
