Air Rings are designed for measuring the outside diameter of parts. Air gaging is a fast and extremely reliable method of measuring. In addition to the diameter, we can measure roundness, perpendicularity, and parallelism. Custom gages can be made with multiple measurement levels for checking straightness or taper. Also many configuration of 2, 3, 4, or more jets can be made per your requirement. Typical uses are in the Automotive, Aerospace, and medical industries but can be used in many additional ones as well.
