We own the largest ceramic ball production line in China,production ability come to be larger than 30,000,000pcs/year,with advanced GPS(Gas Pressure Sintering) or HIP(Heat Isostatic Pressure sintering) technology been applied.Products including precision silicon nitride,zirconia and 99.5%alumina balls with standard and non-standard diameters from 0.8mm to 101.6mm,with quality between Grade 3 and Grade 100.

Application:
Composite bearings, mechanical seals, chemical pumps, nozzles, auto parts, heat exchange components, vacuum equipment and a variety of harsh environment.

Specifications of Silicon Nitride balls:

1) 60% lighter than steel

2) Has elastic modulus 50% larger than that of steel

3) Lower friction coefficient, rolls more freely

4) Coefficient of thermal expansion is only one third of that of steel

5) Superior surface finish

6) High-temperature hardness is twice than that of steel

7) Never rust, and can roll without oil or grease

8) Better corrosion resistant than steel
