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

These alumina ceramic bush sleeves deliver serious protection in punishing conditions. Made from 95% or 99% pure aluminum oxide (Al2O3), they offer exceptional hardness and strength. This material fights wear aggressively, lasting much longer than metal parts in abrasive settings. It keeps its shape under heavy loads and constant friction.

Heat is no problem either. These ceramic sleeves handle temperatures up to 1600°C easily. They stay stable and strong even in extreme furnace zones or near hot machinery. This high temperature ability prevents warping or cracking where other materials fail.

Electrical insulation is another major benefit. The alumina ceramic blocks current flow effectively. This makes the sleeves perfect for isolating components in electrical systems or preventing stray currents in industrial equipment. They prevent short circuits reliably.

The smooth surface finish reduces friction significantly. This cuts down on energy loss and lowers operating temperatures. Moving parts run smoother and last longer. Less friction means less wear on both the sleeve itself and the shaft it protects.

These bush sleeves work well in many tough spots. Use them in high-temperature pumps handling hot liquids or slurries. Install them in demanding valve systems controlling abrasive flows. They protect shafts in industrial furnaces, kilns, and heavy machinery subjected to heat and grit. They are vital in mining equipment, steel plants, and power generation.

Choosing the right purity matters. The 95% alumina grade provides excellent wear resistance and heat tolerance for most heavy-duty uses. The 99% alumina grade offers even better performance. It has higher hardness, superior electrical insulation, and can withstand slightly higher temperatures. It’s the top choice for the most extreme conditions or critical electrical isolation needs.

Installing these sleeves protects expensive machinery. They extend the life of rotating shafts and bearings exposed to heat, abrasion, or electrical risks. Their toughness reduces unplanned downtime. Maintenance costs go down. Overall efficiency improves. They save money over time by replacing weaker parts that wear out fast.

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

High temperature wear resistant ceramic bush sleeves made from 95% to 99% Al2O3 alumina ceramic offer exceptional performance in tough conditions. This material is extremely hard. It resists abrasion far better than most metals. Parts last much longer. This reduces downtime and replacement costs significantly.

Alumina ceramic handles extreme heat very well. It keeps its strength and shape at temperatures where metals soften or fail. This makes it perfect for furnaces, kilns, and high-heat processing equipment. Bushings won’t deform or weaken under thermal stress.

Electrical insulation is another major benefit. Alumina ceramic does not conduct electricity. This prevents electrical arcing or short circuits. It’s essential in motors, generators, and electrical assemblies where metal bushings pose a risk.

Chemical resistance is strong too. Alumina ceramic withstands attack from many acids, alkalis, and solvents. It won’t corrode or degrade like metal parts in harsh chemical environments. This ensures reliable operation in chemical plants or plating lines.

These bush sleeves find use in many demanding applications. They work well as shaft guides in high-temperature pumps and fans. They protect bearings in steel mill rollers and foundry conveyors. They insulate moving parts in electric motors and power generation turbines. They are ideal for harsh material handling systems moving abrasive powders or slurries.

The high purity Al2O3 ceramic provides a very smooth surface finish. This minimizes friction against shafts or bearings. Less friction means less wear and lower energy consumption. Sealing surfaces also benefit from this smoothness.

These components are crucial for reliability. They extend equipment life dramatically. They cut maintenance frequency. They improve safety by preventing electrical hazards. They offer a cost-effective solution for severe industrial challenges. Industries like mining, power generation, steel production, and chemical processing rely on them.

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

High Temperature Wear Resistant Ceramic 95%-99% Al2O3 Insulating Alumina Ceramic Bush Sleeve – FAQs

1. What makes this alumina ceramic sleeve good for high heat?
This sleeve uses 95% or 99% pure aluminum oxide (Al2O3). Alumina ceramic keeps its strength and shape at very high temperatures. It doesn’t melt or weaken easily. Many metals fail under these conditions. This ceramic handles extreme heat reliably.

2. How well does it resist wear?
Alumina ceramic is extremely hard. It ranks just below diamonds. This hardness makes it very resistant to abrasion and scratching. Parts sliding against it cause minimal wear. It lasts much longer than metal parts in abrasive environments. This reduces downtime and replacement costs.

3. Why is it called an insulating sleeve?
Alumina ceramic is an excellent electrical insulator. It does not conduct electricity. This property is crucial in electrical applications. It prevents short circuits. It also provides thermal insulation. Heat doesn’t transfer through it as easily as metal.

4. Can you make custom sizes and shapes?
Yes. We offer custom manufacturing. Tell us the dimensions you need. We can make different inner diameters, outer diameters, and lengths. Complex shapes are possible too. We machine the ceramic precisely to your specifications.

5. How do you install and maintain this ceramic sleeve?
Handle the sleeve carefully before installation. Alumina ceramic is strong but brittle. Avoid impacts. Press-fit installation into a metal housing is common. Ensure the housing bore is clean and correctly sized. Lubrication might help during fitting. Once installed, it needs almost no maintenance. The ceramic won’t corrode or degrade like metal. Just inspect it periodically for cracks. Its smooth surface minimizes friction buildup.
