5 FAQs of Electronical Insulation Industrial 99% Al2O3 Aluminum Oxide Ceramic Bead Bearing

Here are 5 common questions about our 99% Al2O3 Aluminum Oxide Ceramic Bead Bearings:

What exactly is this ceramic bead bearing? It’s a precision ball made almost entirely of aluminum oxide. We use 99% pure Al2O3. This creates an extremely hard, wear-resistant sphere. These beads function like tough bearings or spacers in demanding industrial settings. They handle high loads and harsh conditions.

Why use alumina ceramic? Alumina ceramic offers key advantages. It’s incredibly hard. This means it resists abrasion and wear exceptionally well. Alumina is also chemically inert. Most acids and alkalis won’t affect it. It doesn’t rust or corrode like metal. It withstands extreme temperatures. These properties make it perfect for tough applications.

How hot can these beads get? These 99% Alumina beads perform reliably at very high temperatures. They work continuously up to 1700°C (3092°F). This thermal stability is far superior to metal or plastic bearings. They won’t soften or deform under intense heat. This makes them ideal for furnaces or high-heat machinery.

What chemicals can they resist? These beads resist a wide range of chemicals. Strong acids like sulfuric acid and hydrochloric acid generally don’t harm them. Strong bases like sodium hydroxide also have minimal effect. They resist most solvents and corrosive gases. This inertness is crucial in chemical processing or plating equipment.

Is the surface really hard? Yes, the surface is extremely hard. Alumina ceramic ranks near 9 on the Mohs hardness scale. Only diamond is harder. This hardness means the beads resist scratching, gouging, and surface wear exceptionally well. They maintain a smooth surface finish even under heavy load and friction. This reduces wear on mating parts too.
