Dimension-Over-Ball Gage Measures Spurs, Helical Gears, Splines

United Tool Supply’s Unite-A-Matic gage checks dimension over ball (DOB), dimension over pin (DOP), and major/minor diameter of spurs, helical gears and splines. A variety of models can be used externally or internally to check a gear’s inner or outer diameter. Recent improvements to the gage line include a soft-touch feature that reduces operator interference with the gage head. With plans to develop the Unite-A-Matic into a fully automated machine with interchangeable tooling capable of measuring multiple gears, the company says it is reliable, accurate and robust enough for the shopfloor environment.
