Custom Precision Balls

Bal-tec was established in 1952 to custom produce precision balls that were not commercially available. We manufacture precision balls in any size from 0.005" ( 0.13 mm ) to over 17" ( 400 mm). We manufacture precision balls in any material from plastics to tungsten carbide. We manufacture precision balls from one piece to millions of pieces. We manufacture precision balls that are rounder, with a better surface finish, than any other commercial source; and we have the ability to measure these qualities to a level that few, if anyone, else can.
