Application of bushing in friction pairs to become wear-bearing parts

- Aug 09, 2019-

Bushing is used outside mechanical parts to achieve sealing, wear protection and other supporting parts. Bushing has a wide range of applications, many parts in the industrial field, such as valves, bearings and other components will use bushing.

The function of bushing

Bushing has high flexibility in use, and it can play a lot of roles. Generally speaking, bushing is a kind of component to protect equipment. The use of bushing can reduce the wear, vibration and noise of equipment, and has anti-corrosion effect. The use of bushing can also facilitate the maintenance of mechanical equipment, simplify the structure of equipment and manufacturing process.

The role of 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 cover the valve stem, so as to reduce the leakage of the valve and achieve sealing effect. In the field of bearing application, the use of bushing can reduce the wear between bearing and shaft seat, and avoid the increase of clearance between shaft and hole.

Material of Bushing

The material of bushing is mostly soft metal, rubber, nylon and non-metallic polymer. These materials are relatively soft in texture and low in price. In all kinds of harsh working environments, bushing is subjected to vibration, friction and corrosion to protect the wrapped parts, and the bushing itself is easy to replace after damage, low cost and good economy.

Bushing Type Selection Factor

Bushings have a wide range of applications and many kinds. To choose the suitable bushings, we must consider their use purposes and choose different types of bushings under different working conditions. The main consideration in the selection of bushing type is the pressure, velocity, product of pressure and velocity, and load property. In addition, whether the bushing is lubricated or not determines its service effect and life.
