Elastomer Metal Plastic Silicone Rubber Bushing Washer

Elastomeric Plastic Silicone Rubber Bushing Washer

Bushing washer, knows as Siliocne Rubber bushing Sealing Gasket, Rubber O ring Washer , which made of steel, plastic or made elastomeric rubber materials like MVQ, EPDM, NBR, SBR, FKM, HNBR, NR etc. Some bushing washer made of overmolding plastic + rubber, steel + rubber.
Elastomeric Silicone Rubber Bushing Washer also called as Silicone Rubber Grommets, Rubber Damper, Rubber Bumper, transparent Silicone Sleeves, Silicone Rubber Bellows etc, which made by rubber compression mold tooling.

Plastic Rubber Bushing Washer and Metal Rubber Bushing Washer, which made by silicone rubber overmolding compression molding or Liquid silicone rubber injection molding. If made by rubber overmolding, plastic materials temperature resistance should up to 180^oC like PBT


Rubber Bushing Washer 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 or silicone bushing washer 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 bushing.


Rubber Bushing Washer Usage: The rubber 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. Now, people tend to replace the 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 rubber bushing is in vehicle suspension systems, where a 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 bushing may also be described as a flexible mounting or antivibration mounting.
