DieQua Corporation was founded in 1980 with a single product line. From its conception DieQua’s focus has been to provide products that offer the highest quality, the most unique designs, the most reliable performance, along with superior value. This customer centric focus has allowed them to grow into a much larger organization offering servo gearheads, gearboxes and speed reducers to couplings, screw jacks and cycloidal gear reducers. 

DieQua has a dedicated and knowledgeable team to assist you in specifying the appropriate technology for each individual application. Decades of combined experience specifying power transmission and motion control products allow DieQua to provide component modifications or complete special designs.
