Rubber Sleeve Bush

Rubber sleeve bush playing a role of liner is mostly applied in the field of valve,which is in the valve bonnet , wrapping the valve stem. A bush or sleeve bush 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 silicone sleeve bushing.

Rubber Sleeve Bush Description
Rubber sleeve bush playing a role of liner is mostly applied in the field of valve,which is in the valve bonnet , wrapping the valve stem. A bush or sleeve bush 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 rubber sleeve bushing.
  Rubber Sleeve Bus h  Function
The Rubber sleeve bush can be replaced very conveniently if it is worn out. If you don’t use the liner bush, you have to replace the whole part once abrasion. Now, people tend to replace the bushing bolck (while designing, the hardness of bush 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 rubber sleeve bush  is in vehicle suspension systems, where a silicone sleeve 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 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 silicone  lining bushing may also be described as a flexible mounting or antivibration mounting .
  Rubber Sleeve Bush   Feature
- various hardness for your choice.
- oil resistance.
- good anti-aging performance.
- ease of bonding to other material.
- excellent oxygen and ozone resistance.
- non-flammable,self-extinguish.
- good gas tightness.
- high heat resistance.     
- good abrasion resistance .
