Precision Spheres

Glass and ceramic spheres are used in a wide variety of applications

Examples include:


Used as flow meter balls where red and black balls give clear visibility
Used as gauging and measuring standards


Silicon nitride balls are used in high-speed bearings because of their superb wear properties, light weight and low thermal expansion.
Large zirconia balls are used in down hole drilling applications in the oil industry where they resist wear from abrasive particles.


Spherical and hemispherical ball lenses are used in fiber optic and laser applications.
They can be anti-reflection coated to significantly improve optical transmission.


Glass and ceramic balls are used in check valves where corrosive chemicals are being pumped.
