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

This alumina ceramic bush sleeve handles extreme heat and heavy wear. It contains 95% to 99% pure aluminum oxide (Al2O3). This high purity makes it incredibly hard. It withstands temperatures up to 1700°C. This material resists abrasion very well. It lasts much longer than metal parts in gritty conditions. It also resists most strong acids and alkalis. This prevents chemical damage.

The ceramic is an excellent electrical insulator. It has high dielectric strength. This makes it safe for electrical applications. It prevents unwanted current flow. The bush sleeve keeps its shape under high heat. Its thermal expansion is low. This ensures stable performance in hot environments.

We machine these sleeves precisely. Tolerances are tight. This ensures a perfect fit. The surface finish is very smooth. This reduces friction and wear on mating parts. Different sizes and shapes are available. We can make custom designs. This meets specific machine needs.

These bush sleeves are ideal for tough jobs. Use them in mining equipment, pumps, valves, and heavy machinery. They protect shafts and rods. They reduce wear in high-temperature zones. They work well in electric motors and generators. They provide insulation and prevent seizing. They perform reliably in harsh chemical settings. They are a good choice for long-lasting parts under stress.

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

This alumina ceramic sleeve handles extreme heat and constant wear. Its 95% to 99% pure Al2O3 composition delivers outstanding performance. It withstands temperatures exceeding 1500°C easily. This makes it perfect for demanding furnace environments. Think kiln furniture supports, burner nozzles, or thermocouple protection tubes. It keeps things running hot without breaking down.

Hardness is another major strength. This ceramic rates over HRA 88. That’s much harder than most metals. Abrasion barely scratches it. This toughness is vital in gritty settings. It excels as liners inside pumps moving corrosive slurries. It protects pipes carrying abrasive powders. It serves well as wear plates in heavy machinery like crushers. Mining and cement plants rely on this durability daily.

Electrical insulation is key. This alumina ceramic blocks current flow effectively. It stays non-conductive even at peak temperatures. This property is crucial for isolating high-voltage components. You find it in electrical feedthroughs for heaters. It insulates spark plug bodies reliably. It isolates elements within industrial heaters safely.

Chemical resistance adds value. The material shrugs off most acids and alkalis. Harsh chemicals don’t degrade it. This is essential for chemical processing equipment. Valves handling corrosive fluids use these sleeves. Pump seals in tough chemical plants depend on them. Reactor components benefit from this inertness.

For moving parts, its low friction coefficient matters. Metal shafts rotate smoothly within these bushings. They reduce wear on both the shaft and housing. This extends equipment life significantly. Steel mills use them in roller guides. Textile machinery employs them for smooth operation. Packaging lines install them for reliable motion.

Its light weight compared to metals is a practical bonus. Installation is easier. Loads on supporting structures decrease. This matters in complex assemblies or retrofits. Think aerospace sensors or semiconductor manufacturing tools. Reducing weight improves efficiency.

Thermal shock resistance is impressive. It survives rapid heating and cooling cycles. This is critical where temperature changes happen fast. Power generation equipment needs this reliability. Foundry tools demand this stability. Automotive sensors perform consistently because of it.

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

What are these alumina ceramic sleeves?
They are tubes made from 95% or 99% pure aluminum oxide (Al2O3). This material is incredibly hard and durable. These sleeves act as protective liners or bushings. They shield parts from extreme heat and constant rubbing.

How hot can they handle?
These alumina sleeves withstand very high temperatures. They work reliably long-term up to around 1600°C (2912°F). Short exposure to even higher heat is possible. This makes them ideal for furnaces, kilns, and hot machinery parts.

Why are they good against wear?
The high alumina content makes them extremely hard. This hardness is close to diamonds. Hard materials resist scratching and erosion much better. Constant friction from moving parts causes less damage. They last longer than metal parts in abrasive conditions.

Do they conduct electricity?
No, they are excellent electrical insulators. Alumina ceramic does not conduct electricity. This property is crucial in electrical applications. It prevents short circuits. It also protects components from stray currents. They insulate effectively even at high temperatures.

Where are they typically used?
You find these bushings in demanding industrial jobs. Common uses include high-temperature furnace rollers and conveyor systems. They protect pump shafts and mixer blades. They insulate thermocouples and heating elements. They are essential in steel, glass, power generation, and mining equipment exposed to heat and abrasion.
