Ceramic Washer Spacer Alumina Zirconia Ceramic Ring For Industrial Parts

Ceramic washer spacer adopts ceramic material, which is the material with the best rigidity and the highest hardness in engineering materials,  like:95%--99.99% Alumina(Al2O3), Zirconia(ZrO2) ,Silicon Carbide,Silicon Nitride ...etc which have a excellent Physical properties,Mechanical properties,Electrical properties,Thermal properties. Wear hardness strength resistance.

Due to the industry, the use of ceramic washer should be different industries or equipment, wsher have a variety of designs, and within the scope of these individually designed washer materials, size changes and surface treatment.ceramic washer use under different fasteners, bolts or screws.The customer can be used as a screw or bolt on a component with a nut or encapsulation.Most washers are sized to match the components they will use.

Ceramic washer accessories ring: Ceramic flat washer Ceramic corrugated washer Ceramic toothed washer Ceramic ring washer Ceramic lens washer Ceramic o-ring pad

The ceramic ring washer can be divided into: Octagonal ceramic ring pad Oval ceramic ring pad RX and BX self-sealing ceramic washers
