Unasis provide a wide range of ceramic ball options across a variety of sizes. Material options include Silicon nitride (Si3N4), Zirconia (ZRO2) and Silicon carbide (SIC) from 0.4mm to just over 115mm in diameter with the most common sizes in between. Precision grades provided are 5, 10, 16, 25 and 100.
Ceramic balls have excellent resistance to wear and seizure, they offer solutions for high temperature environments (Up to 800°C for Si3N4) high rigidity, light weight and are non magnetic with insulating properties.
Applications include high speed spindle bearings, solenoid valves, down hole pumps, vacuum equipment, gas monitoring devices and turbo chargers.
Ceramic Ball Part Numbering System
Ball Diameter as a decimal including units. Example 6.35mm or 0.5″
Cage / Separator
A large variety of grades are available from GD5 and up. Precision grade is dependent on the size of ball required.
SI = Silicon Nitride, ZR = Zirconia, SC = Silicon Carbide
