5 FAQs of Al2O3 Ceramic Bushing Sleeve for Mechanical, Electrical, and Thermal Insulation

What is Al2O3 ceramic?
Al2O3 ceramic means aluminum oxide ceramic. It’s a very hard material. People also call it alumina ceramic. It’s made by pressing aluminum oxide powder and firing it at high temperatures. This process makes it dense and strong.

Why use Al2O3 ceramic for bushings?
Al2O3 ceramic bushings handle extreme conditions well. They resist very high heat. They block electricity effectively. They are also very hard and resist wear. This makes them ideal for insulating shafts or rods in tough environments where plastic or metal might fail.

How much heat can these bushings take?
Al2O3 ceramic bushings handle continuous temperatures up to about 1600°C (2912°F). They manage short bursts even higher. This is much better than most plastics or metals. They won’t melt or deform at these high temperatures.

Are these bushings good electrical insulators?
Yes, they are excellent electrical insulators. Al2O3 ceramic has high electrical resistance. It stops electric current flow. This protects equipment. It prevents electrical shorts. It is vital in high-voltage applications or where electrical isolation is critical.

How are these ceramic bushings installed?
Install them carefully. The ceramic is hard but brittle. Avoid impacts or excessive force during pressing. Make sure the mating metal parts have smooth surfaces. The ceramic’s surface finish is usually very smooth. This helps create a good seal with other components. Proper sizing and gentle handling prevent cracking.
