Aluminum oxide ceramic motor shaft sleeve

Aluminum oxide ceramic motor shaft sleeve is a high-performance industrial ceramic component mainly used in electric motors and other high load, high-speed equipment.

High hardness: Alumina ceramic materials have extremely high hardness, usually reaching HRA 92 or above, ensuring their wear resistance.
High temperature resistance: capable of withstanding temperatures up to 1650C, suitable for high-temperature working environments.
Corrosion resistance: It exhibits good stability in acidic media and is suitable for corrosive environments.
High mechanical strength: With high mechanical strength, it ensures stable performance in high-pressure environments.
Good insulation performance: It has a high insulation resistance and is suitable for applications that require electrical insulation.

The detailed description of alumina ceramic shaft sleeve is as follows:
Material composition:
99% Al2O3 ceramic
99.5% Al2O3 ceramic
99.7% Al2O3 ceramic
Physical performance:
Bulk density: 3.9 g/cm ³
Hardness: HRA 92 or above
Dielectric constant: 9.7
Maximum operating temperature:> 1650C
Breakdown voltage: 33KV/MM

Structural design:
The surface of the inner cavity adopts a fluid structure, with no dead corners or grooves, making it easy to clean and disinfect.
The shaft sleeve is connected to the magnet as a whole, avoiding wear and extending its service life.
Adopting isostatic pressing molding ensures consistency in density and improves the mechanical properties and heat resistance of the product.

Application areas:
Widely used in electric motors, brushless DC magnetic drive water pumps, magnetic isolation water pumps, ceramic shaft sleeves, etc.
