Product Details
The Zirconia full ceramic single-direction thrust ball bearing is a high-performance bearing engineered for precision, durability, and chemical resistance. It is manufactured with zirconia (ZrO₂) inner and outer rings and ZrO₂ ceramic balls, combined with a PTFE cage for smooth and stable operation, delivering superior performance compared to traditional steel bearings, especially in demanding environments.
Compared with conventional bearing steel, zirconia ceramic bearings perform significantly better in chemically aggressive and electrically sensitive environments.

The PTFE cage offers low friction, good chemical stability, and reliable performance at both high and low temperatures.
Designed to handle axial loads in a single direction, this bearing provides high precision and smooth rotation under thrust conditions while maintaining full ceramic advantages, including:
- High corrosion resistance for aggressive chemical environments
- Exceptional hardness and wear resistance for long-lasting durability
- Electrical insulation for safe use in electronic applications
- Low friction and smooth operation for reduced heat and extended service life
- Lightweight design for improved energy efficiency and dynamic response

Frequently Asked Questions
- Lighter weight
- Higher wear and corrosion resistance
- Electrical insulation
- Operates at higher temperatures
- Lower friction and longer service life in precision applications
Yes. Zirconia is chemically inert and biocompatible, making it suitable for chemical, pharmaceutical, and medical applications.
Yes. They offer lower friction and higher stiffness than steel bearings, making them ideal for precision and high-speed machinery.
- Avoid contamination with hard particles
- Use compatible lubricants (ceramic bearings can be used dry in some cases)
- Inspect periodically for wear, especially in high-speed or high-load applications
Yes, but ensure that the bearing housing and lubrication are compatible, and that the load and speed requirements do not exceed ceramic material limits.
