Ceramic sleeves bushing for shaft liner fiber optic with zirconia alumina
The ceramic sleeve is a new type of sleeve that is resistant to high temperatures, high pressure, corrosion and insulation. The sleeves are made of alumina ,zirconia and other advance ceramic material. It has the ability to work continuously without oil lubrication at high temperatures. It has broad application prospects in the fields of electronics, aviation and chemical industry.
Ceramic sleeve mainly have shaft sleeve, sleeve liner, sleeve bear, fibe optic sleeve connector with excellent proerties:
·Excellent physical & chemical stability ·High temperature resistance(1050-1750℃)
·Excellent wear & pressure & corrosion& insulation resistance and thermal conductivity.
High Durability
