Product Overview

Zirconium Oxide Balls are refractory ceramic balls engineered for high wear resistance, high temperature stability, and extended service life in corrosive and erosive environments. Refractory ceramic balls offer exceptional resistance to rust, wear, and heat. When they are subjected to impacts, they get harder. A high-strength material performs well at temperatures up to 1000°F and functions successfully in various environments, including molten metal, organic solvents, caustics, and most acids. In some applications, zirconia oxide endures in corrosive and erosive environments two to three times longer than metal or carbide. Being lighter also helps to minimize damage to mated components.

Engineered and tested across thousands of installations based on decades of manufacturing expertise, Zirconium Oxide Balls are selected for precision motion and sealing interfaces where chemical inertness, thermal stability, and controlled precision grades are essential. These balls are widely used in special bearings, control valves, pumps and valves operating in corrosive environments, petroleum equipment pumps, flowmeters, measuring instruments, safety valves, the medical field, and grinding applications.
