Bushing Description
Silicone bushing, acting as a liner, is primarily used in valve applications, located in the valve bonnet and wrapping the valve stem. A bushing or silicone bushing is a type of vibration isolator that provides an interface between two parts, damping energy transmission and absorbing shocks while reducing vibrations through the bushing.
 
 Bushing Function
The bushing can be replaced very conveniently if it is worn out. If you don't use the bushing, you have to replace the whole part once abrasion occurs. Now, people tend to replace the bushing (while designing, the hardness of the bushing can be reduced to serve as a bearing grinding of the friction pair), due to its convenient processing, low replacement cost, and ease of replacement. It also includes other secondary functions such as guiding function, among others.
 
A common application of bushing is in vehicle suspension systems, where a bushing made of rubber (or more often, synthetic rubber or polyurethane) separates the faces of two metal objects while allowing a certain amount of movement. This allows the suspension parts to move freely, for example, when traveling over a large bump, while minimizing the transmission of noise and small vibrations to the chassis of the vehicle. A silicone bushing may also be described as a flexible mounting or anti-vibration mounting.
