In the production of ceramic bearing bushings, the commonly used ceramic materials are Alumina ceramic, Zirconium ceramic and Silicon carbide. Their unique characteristics and advantages are as following.

Properties and advantages of Alumina (Al2o3) Ceramic Bushings:
Good wear resistance: Alumina ceramic has good wear resistance, enabling it to withstand high speed rotation and high load conditions in bushing applications.
Corrosion resistance: Alumina ceramic has good corrosion resistance, enabling it to operate stably for long periods of time in harsh environments.
Good machinability: Alumina ceramic is easy to machine and economical to produce.

Zirconia (ZrO2)  Ceramic bushing characteristics and advantages:
High hardness and strength: Zirconia has very high hardness and strength, which makes it have excellent wear resistance under high speed and high load conditions.
Excellent corrosion resistance: Zirconia has good corrosion resistance and can operate stably for a long time in corrosive environments.

Silicon carbide (SiC) bushing features and advantages:
High hardness and wear resistance: Silicon carbide has excellent wear resistance, enabling it to provide stable performance at high speeds and under high loads.
Good heat resistance: Silicon carbide is able to maintain stable performance in high-temperature environments.
Excellent thermal conductivity: Silicon carbide has good thermal conductivity, which helps dissipate heat under high temperature conditions.
More difficult to process and more expensive to produce
