Silicone Bushing
Silicone bushing playing a role of liner is mostly applied in the field of valve,which is in the valve bonnet , wrapping the valve stem. A silicone bushing or rubber bushing block is a type of vibration isolator, it provides an interface between two parts, damping the energy transmitted and to absorb shock and reduce vibration through the suspension rubber silent bushing .
Description
Silicone bushing playing a role of liner is mostly applied in the field of valve,which is in the valve bonnet , wrapping the valve stem. A bushing Block or rubber bushing block is a type of vibration isolator, it provides an interface between two parts, damping the energy transmitted and to absorb shock and reduce vibration through the suspension rubber silent bushing .
Function
The Silicone bushing can be replaced very conveniently if it is worn out. If you don’t use the bush block, you have to replace the whole part once abrasion. Now, people tend to replace the rubber damper bushing bolck (while designing, the hardness of bushing can be reduced to be a bearing grinding of friction pair), due to its convenient processing, low replacement cost and easy replacement, of course, also including other secondary functions, like guiding function, and etc.
A common application of Silicone bushing block is in vehicle suspension systems, where a sleeve bushing block 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 movement allows the suspension parts to move freely, for example, when traveling over a large bump, while minimizing transmission of noise and small vibrations through to the chassis of the vehicle. A poly bush may also be described as a flexible mounting or antivibration mounting .
