At Bal-tec™, quality is of the utmost concern. We use the Talyrond System to measure sphericity of balls. The overall accuracy of this system is one-millionth of an inch.
The size of balls are measured using a Heidenhain Certo 60 to an accuracy of 10-millionths of an inch and is calibrated using standards traceable to NIST.
Most balls are produced to the Anti-Friction Bearing Manufacturers Association (A.F.B.M.A. Book 10), military specifications, or our customers’ needs.
Bal-tec™ stocks over 40,000 different sizes, grades and materials of balls.
