The bushing is a supporting part used externally on mechanical components to achieve sealing, wear protection, and other functions, referring to a ring bushing that serves as a cushion. In the field of valve applications, the bushing is located inside the valve cover, typically made of corrosion-resistant materials like polytetrafluoroethylene or graphite, for sealing purposes.

The function of the bushing

The flexibility of the bushing use is quite high, and it can serve many functions. In summary, the bushing is a type of component that protects equipment. The use of the bushing can reduce equipment wear, vibration, and noise, and it also has anti-corrosive effects. The use of the bushing can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of the equipment.
The actual function of the bushing in work is closely related to its application environment and purpose. In the field of valve applications, the bushing is installed in the valve cover to encase the valve stem, thus reducing valve leakage and achieving a sealing effect. In bearing applications, the use of the bushing can reduce wear between the bearing and bearing housing, preventing the clearance between the shaft and the hole from increasing.

Material of the bushing

The material of the bushing is mostly soft metals, rubber, nylon, and non-metallic polymers, all of which tend to be relatively soft and economically priced. In various harsh working environments, the bushing withstands vibrations, friction, and corrosion to protect the components it envelops, while the bushing itself is easy to replace, low-cost, and economically favorable after damage.
