DieQua Corporation is a sequential gearbox manufacturer and supplier of a wide range of motion control and power transmission drive components. Our focus has always been to provide products that offer the highest quality, the most unique designs, the most reliable performance, along with superior value. Not resting on our past accomplishments, DieQua continues to search the world over for innovative products to meet the changing technological needs of the industries we serve. As we introduce them, you can expect to see updates to this website. Founded in 1980 by Dietmar Quaas, with a single product line, we have since grown into a unique organization offering not only the greatest variety of gearboxes, speed reducers, and connecting components, but also the expertise and experience to help select and specify the appropriate technology for each individual application. It’s through our consultative approach that we are most helpful to our customers in finding the best design solution.
