The ceramic bushing have a excellent high temperature resistance performance for the industrical application or ceramic parts which use in special environments. the max use temperature of Alumina ceramic bushing can be up to 1750 ℃，and the zirconia ceramic bushing be up to 1050 ℃. ceramic bushing as a kind of industrical ceramic parts, it’s mostly use for industry parts in difference temperature environment. Ceramic bushing with excellently High temperature ability will help the parts to Extended service time.
The wear and high pressure performance of ceramic bushing:
Ceramic bushing made from advance ceramic materials sush as alumina,zirconia, siliconia etc. The property of the advance ceramic have a better wear and high pressure resistance.so that the ceramic bushing with the wear and high temperature resistance have better performance for the industry parts which used for the connected parts.
1.High temperature tolerance
