Product Description
Mechanical ceramic silicon carbide seal ring
Product Description
we can supply ssic/sic/carbon/TC/NBR/Viton
pump part,o ring,face seal, mechanical seal,sic seal
bearing and tubes
sic blank has the advantages of excellent corrosion resistance,high coefficient of heat conductivity,self-lubricity,small expansion.It can be widely used in the petroleum,chemical,machinery-building,cosmonautics and motors industries.The frictional factor of combination of silicon carbide and carbon graphite is the least,so it widely applied to high characteristics for mechanical seals .
