Air Rings
Air Rings are used to inspect the true or average outside diameter of cylindrical parts and can reveal conditions of cloverleaf, taper or out-of-roundness. They are manufactured in many different types, shapes, and sizes and can be designed for presenting the part to the gage or the gage to the part. They can be used with Precisionaire or A/E Column Instruments. Air Rings are made of long wear life steel and can be chrome plated or TiN coated for even longer durability. A part print, sample part or any special requirements should be submitted with an inquiry.

Standard Thru and Shoulder Type Air Rings
Standard hand held Thru and Shoulder Type Air Rings cover a range of parts from .240 through 6.010. Thru Type Air Rings feature two diametrically opposed air jets centered in the ring. Shoulder Type Air Rings have the two jets located as close to the edge of the air ring as possible. Where "clover leaf" conditions exist, three-jet air rings are available for checking average diameter. For part-to-gage applications, a gaging stand is used.
