1.Exceptional Wear Resistance
High Hardness & High Toughness: Zirconia offers extreme hardness, while its unique "transformation toughening" mechanism grants it fracture toughness far superior to other ceramics. It effectively resists abrasive wear and impact loads, resulting in an exceptionally long service life.
2.Ultimate Corrosion Resistance
Chemical Inertness: It is perfectly resistant to most strong acids, strong alkalis, and organic solvents, completely free from rust or chemical corrosion, enabling stable operation in highly corrosive media.
3.Excellent Self-Lubrication & Low Friction
Under boundary lubrication and dry-running conditions, Zirconia exhibits a relatively low coefficient of friction against various counterfaces, enabling smooth operation, especially during start-up and shutdown.
4.Superior High-Temperature Performance
Capable of maintaining its mechanical properties and dimensional stability at temperatures up to 800°C, without oxidizing or softening.
5.Other Key Properties
Electrical Insulation: A perfect insulator, preventing electrical erosion caused by stray currents.
Non-Magnetic: Completely free from magnetic interference.
Low Density: Lightweight, helping to reduce inertia in high-speed moving parts.
Working Principle
Zirconia Sliding Bearings fall under the category of Plain Bearings or Sleeve Bearings, operating on the principle of sliding friction:
1.Sliding Interface: The bearing acts as a stationary sleeve, forming a sliding pair with the shaft (or journal) that rotates or slides within it.
2.Media Adaptation:
Fluid Film Lubrication: Ideally, the pumped fluid itself can form a lubricating film between the shaft and the bearing.
Boundary Lubrication & Dry-Running: Under harsh conditions with a lack of effective lubrication, Zirconia's inherent high wear resistance and low friction allow it to slide directly against the shaft, protecting the shaft from damage and maintaining equipment operation.
Core Function: It supports the shaft and ensures its precise rotational alignment by either sacrificial wear (which is minimal) or its superior anti-friction capabilities, while simultaneously isolating it from chemical and electrochemical attack.
Application Scenarios
Zirconia Sliding Bearings are the ultimate choice for the following demanding applications:
Extreme Chemical Processing: Pumps, valves, and agitators handling highly corrosive media like concentrated acids, alkalis, and solvents.
High-Purity & Pharmaceutical Industry: Bioreactors, pharmaceutical transfer pumps, ensuring absolute zero metallic ion contamination and resistance to CIP/SIP cleaning.
Food & Beverage Processing: Used in pumps for viscous or corrosive foods like sauces and syrups, in production lines where lubricants are prohibited.
Abrasive Slurry Handling: Slurry pumps in mining and ceramic industries, effectively resisting wear from fluids containing hard particles.
Special Environments: High-temperature ovens, vacuum environments, and electric motors and equipment requiring electrical insulation.
