Bushing is a type of mechanical components used to reduce friction between objects, can be integral in order to format the specification of motion and reducing an abrasive wear. Bearing, in power-transmitting machine part, a support or guide so as to permit the shaft (or other moving part) to turn freely replace by Bushing.With varying specifications they are ideal for reducing friction between 2 parts, some of its function includes providing a bearing surface for rotary applications, contribute wearing and tear reduction. Bushings are also available in bronze, steel and plastic-like materials to absorb the load of bearing a tool or various environmental conditions on the mechanical operation of power tools which offer technical experience. These components take different sizes and shapes and are used in a variety of applications such as automotive systems, industrial machinery, or aerospace equipment hence form an essential part of modern mechanical engineering.
