Specifications of High Alumina Ceramic Ball Bearings 2.5mm 3.5mm 8.56mm 99% Al2O3 Support Media Alumina Balls

These high alumina ceramic round bearings are made from 99% Al2O3. They are available in particular sizes: 2.5 mm, 3.5 mm, and 8.56 mm. This product selection provides crucial residential properties. They are very hard. This hardness implies they stand up to put on exceptionally well. They last a long period of time also under challenging problems.

Warm resistance is another big advantage. These spheres manage really high temperatures easily. They function fine in hot atmospheres where steel parts would fail. They also stand up to chemical attack highly. Acids and antacids normally don’t harm them. This makes them ideal for harsh chemical procedures.

Electric insulation is a vital function as well. The alumina ceramic does not conduct electricity. This protects against electric currents from going through the rounds. They are safe for electrical applications. Magnetic fields do not impact them either. They are non-magnetic.

The surface of these rounds is really smooth. This smoothness reduces friction. Moving parts run much more successfully. Much less power is squandered as heat. They additionally have a reduced thermal development price. Their size stays stable when temperature level adjustments. This is essential for accuracy equipment.

These alumina rounds are ideal for requiring assistance duties. They function well in bearings, pumps, valves, and circulation meters. They are perfect for corrosive environments. They carry out dependably in high-temperature setups. Their security makes them outstanding for accuracy tools. They use a trustworthy, lasting service.

Applications of High Alumina Ceramic Ball Bearings 2.5mm 3.5mm 8.56mm 99% Al2O3 Support Media Alumina Balls

High alumina ceramic ball bearings offer exceptional performance. They are made from 99% aluminum oxide (Al2O3). This material is very hard. It resists scratches and wear extremely well. These balls handle high temperatures easily. They work fine in very hot environments. Chemical resistance is another major benefit. They withstand strong acids and bases. They do not corrode. This makes them safe for sensitive processes. They are also non-magnetic and non-conductive. Electrical interference is not a problem.

These properties create many uses. The 2.5mm size is ideal for precision jobs. Think small valves or delicate instruments. They provide smooth, reliable movement. They are perfect where space is tight. The 3.5mm balls are a versatile middle size. They fit well in pumps and flow meters. They ensure consistent operation. They are common in analytical equipment. The larger 8.56mm balls handle tougher jobs. They support heavier loads effectively. They are excellent in grinding media applications. They mix and mill materials efficiently.

These balls serve as reliable support media. They separate components in reactors. They prevent sticking. They maintain even flow paths. The chemical inertness is crucial here. It prevents contamination of products. This is vital in pharmaceuticals and food processing. The high purity matters. It ensures no unwanted elements leach out. The hardness guarantees long service life. They outlast metal balls significantly. They reduce maintenance costs. They minimize downtime. They are essential in harsh chemical plants. They function where metals fail. They are indispensable in semiconductor manufacturing. Cleanliness is paramount there. The heat resistance suits furnace applications. Thermal shock is not an issue.

5 FAQs of High Alumina Ceramic Ball Bearings 2.5mm 3.5mm 8.56mm 99% Al2O3 Support Media Alumina Balls

What makes these alumina balls different?
They are 99% pure Al2O3. This high purity makes them incredibly hard. They resist wear much better than steel or plastic balls. They last longer in tough conditions.

Can they handle high heat?
Yes. These balls work perfectly in very hot environments. They withstand temperatures up to 1650°C (3000°F). Steel balls would fail or deform at these levels. They are ideal for furnaces or hot processes.

Do chemicals damage them?
No. Alumina is chemically inert. Acids and bases don’t affect them. Solvents won’t harm them either. They are perfect for chemical pumps, valves, or reactors. They won’t rust or corrode like metal.

What sizes do you offer?
We provide three key sizes: 2.5mm, 3.5mm, and 8.56mm. These sizes suit many precision applications. They fit standard bearing assemblies and support structures. Other sizes might be available upon request.

Where are they typically used?
Use them wherever smooth, reliable rotation is critical under harsh conditions. Common uses include precision bearings in pumps, valves, and meters. They serve well as support media in reactors. They perform in high-wear, high-temperature, or corrosive settings. They replace metal balls where failure is unacceptable.
