In producing of ceramic bearings, Alumina ceramics have following superior properties:
Wear resistance: Alumina ceramics have excellent hardness and wear resistance, enabling them to maintain stable performance at high rotational speeds and under high load conditions.
Corrosion resistance: Alumina ceramics have excellent corrosion resistance, enabling them to operate stably for long periods of time in harsh environments.
High-temperature stability: Alumina ceramics can maintain stable performance in high-temperature environments and are not easily affected by thermal expansion.
Low friction coefficient: alumina ceramics have smooth surface and low friction coefficient, which is conducive to reducing energy loss and prolonging service life.
Therefore, alumina ceramics are widely used in ceramic bearings, especially in mechanical equipment requiring high speed, high temperature and corrosion resistance.
