5 FAQs of High Temperature Wear Resistant Ceramic 95%99%al2o3 Insulating Alumina Ceramic Bush Sleeve

What is this ceramic bush sleeve?
It’s a tube made from alumina ceramic. Alumina ceramic contains 95% to 99% aluminum oxide (Al2O3). This material is very hard. It resists wearing down. It handles high heat well. It also stops electricity from passing through. These sleeves protect shafts or pins. They act as bearings or insulators.

Why choose alumina ceramic for high heat?
Alumina ceramic stays strong at extreme temperatures. It won’t melt or deform easily. Most metals weaken significantly above 1000°C. Alumina ceramic keeps working reliably up to 1600°C or higher. This makes it perfect for furnaces, kilns, or hot machinery parts. It won’t fail under intense thermal stress.

How well does it resist wear?
Its hardness is exceptional. Alumina ceramic ranks just below diamond on the Mohs scale. This hardness gives it outstanding abrasion resistance. It withstands constant rubbing against metal, minerals, or other tough materials. It lasts much longer than metal bushings in abrasive conditions. This reduces maintenance costs.

Where are these bush sleeves typically used?
They are common in harsh industrial settings. Look for them in steel plants near furnaces. Find them in mining equipment handling rock. They are in power generation systems needing electrical insulation. They serve in chemical processing with corrosive materials. Any place needing wear resistance, high temperature tolerance, or electrical insulation uses them.

Can I get custom sizes?
Yes, manufacturers offer custom sizing. You provide the exact inner diameter, outer diameter, and length needed. The high purity alumina ceramic can be precisely shaped. This ensures a perfect fit for your specific machinery application. Custom sizes prevent operational issues.
