Gage Balls are frequently used in gauging applications.
Gage Balls and Ball Plug Gages can be used for checking: The size of a Radius, Pitch diameter of screw threads or gears, the centerline dimension between holes. Calibrate other inspection instruments.
Our Custom Precision Gage Balls are an excellent way to check bore diameters. Because of the line contact you can detect if the hole is barrel shape (large in the center), bellmouth (small in the center), or tapered. Balls can be inserted into holes quickly because there are no alignment problems.
Ball Plug gages (guages)- We commonly attach a stem to a ball for use as a plug gage. Two plug gages can be mounted in a standard AGD handle to make a Go/No Go Ball Gage. The Ball Plug Gages can be manufactured to X, XX, or XXX tolerances. The Ball plug gages can be modified with a flat to measure blind holes or otherwise modified to meet your unique application.
