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

This alumina ceramic bush sleeve uses high-purity aluminum oxide (Al2O3). We offer two material grades: 95% Al2O3 and 99% Al2O3. The higher purity 99% version gives better performance. This sleeve handles intense heat well. It works reliably in environments up to 1600°C (2912°F). This makes it much better than many metals or plastics in hot conditions.

It resists wear extremely effectively. The surface is very hard. It typically has a Vickers hardness rating over Hv1500. This hardness means it stands up to abrasion and friction. It lasts longer than softer materials in rubbing or sliding applications. The sleeve also provides excellent electrical insulation. It stops current flow effectively. This is crucial in electrical equipment or high-voltage settings.

Chemical stability is another key feature. It doesn’t react easily with most acids and alkalis. This makes it suitable for corrosive environments. The material is also very dense. This density contributes to its strength and wear resistance. You get a strong, reliable component.

These bush sleeves fit many demanding applications. Use them in furnace parts, kiln furniture, or high-temperature sensors. They work well in pump seals, valve guides, and wear plates. They are common in mining equipment, power generation components, and chemical processing machinery. The sleeves guide shafts, reduce friction, and insulate parts.

The benefits are clear. This sleeve offers long service life under tough heat and wear. It reduces maintenance frequency and downtime. It provides reliable electrical isolation. The material is dimensionally stable at high temperatures. It doesn’t warp or change size easily. This stability ensures consistent performance. Using this sleeve saves money over time. It replaces parts less often and handles extreme conditions effectively. Various sizes are available to match your specific machinery needs.

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

Alumina ceramic bush sleeves made from 95% to 99% Al2O3 offer exceptional performance. This material withstands intense heat easily. Components handle temperatures over 1500°C. This makes them perfect for extreme heat environments. Steel mills, foundries, and power plants rely on them. Furnace rollers, burner nozzles, and thermocouple tubes use these sleeves. Heat won’t damage them quickly.

These sleeves are incredibly hard. They resist abrasion far better than metal parts. Sand, dust, and harsh powders cause minimal wear. Mining equipment, material handling systems, and pump shafts benefit greatly. Machinery lasts longer. Maintenance costs drop significantly. Downtime reduces.

Electrical insulation is another major advantage. Alumina ceramic does not conduct electricity. This is vital in electrical applications. High voltage equipment stays safe. Bushings and insulators in power generation and transmission use these sleeves. They prevent dangerous electrical shorts. Operators stay protected.

Chemical resistance is also strong. Most acids and alkalis don’t affect the material. Chemical processing plants use these sleeves reliably. Valves, pumps, and agitators handle corrosive fluids better. The material stays stable. Performance doesn’t degrade.

The smooth surface finish minimizes friction. Moving parts operate more efficiently. Less energy gets wasted. Seals last longer too. This improves overall system reliability. Bearings and guides run smoother.

Installation is straightforward. These sleeves fit standard shafts. They replace metal bushings directly. Operations see immediate benefits. Equipment handles tougher conditions. Production increases.

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

Customers often ask about our high temperature wear resistant ceramic bush sleeves. Here are common questions answered simply. What is this ceramic made from? It uses 95% or 99% pure aluminum oxide, called alumina. Alumina is very hard and stable. This makes the bush sleeve tough and long-lasting.

How hot can it handle? These alumina bush sleeves resist extreme heat. They work well continuously above 1500°C. Some grades handle even higher temperatures short term. They don’t melt or weaken much. This makes them good for furnaces, kilns, and hot processes.

Is it really wear resistant? Yes, very much. Alumina ceramic is extremely hard, second only to diamond. This hardness fights abrasive wear effectively. The bush sleeve surface stays smooth. It lasts much longer than metal parts in gritty conditions. It saves money on replacements and downtime.

Does it conduct electricity? No, it does not. Alumina is an excellent electrical insulator. Even at high temperatures, it blocks electric current well. This prevents short circuits. It is safe around live electrical parts or high voltages. It is used in electrical insulators and feedthroughs.

Where are these bush sleeves typically used? You find them in tough industrial jobs. They guide shafts and rollers in steel mills, cement plants, and power stations. They protect equipment in mining and material handling. They insulate in high-temperature electrical systems. They are essential where heat, wear, and electrical safety matter.
