Basic concept of bushing

The role of the bushing

Bushings have a high degree of flexibility in use, and they can do a lot of work. In general, bushings are a type of component that protects equipment. The use of bushings reduces equipment wear, vibration and noise, and has an anti-corrosion effect. The use of bushings also facilitates the maintenance of mechanical equipment, simplifies the structure and manufacturing process of the equipment.

The role of the bushing in actual work has a lot to do with its application environment and purpose. In the field of valve applications, the bushing is placed inside the valve cover to cover the valve stem to reduce leakage of the valve and achieve sealing. 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.

Bushing material

The material of the bushing is mostly soft metal, rubber, nylon and non-metal polymer. These materials are relatively soft in texture and low in cost. The bushing is subjected to vibration, friction and corrosion in a variety of harsh working environments to protect the wrapped components, while the bushing itself is easily replaced, cost-effective and economical.

Bushing selection factor

Bushings have a wide range of applications and a wide variety of types. To choose a suitable bushing, it is necessary to consider its purpose of use. Different types of bushings are selected for different working conditions. The main considerations in bushing selection are the pressure, speed, pressure velocity product and load characteristics that the bushing is subject to. In addition, whether the bushing is lubricated or lubricated also determines its use effect and life.
