Speed Reducers

Cotta’s long tradition of manufacturing the highest quality gearboxes, American-made for more than a century, is exemplified in our extensive line of speed reducers and speed increasers. Our speed reducers match the optimum engine speed to the optimum driven equipment speed, allowing your engine and load to both operate at ideal efficiency. Typical uses include pumps, dredges, compressors, crushers, drills and high-performance machinery for oil & gas, construction, mining, and other industrial applications. Our heavy-duty gearboxes are designed for use with diesel engines, electric motors, PTO’s, and other prime movers.

Cotta speed reducers require rear supports and are designed to be driven clockwise facing the input shaft. For us to recommend a speed reducer, we need to know your input speed, ideal output speed, flywheel housing size, flywheel connection requirement, direction of rotation, and the type of driven equipment. If one of our pre-designed units listed below doesn’t fit your need, then our engineering team will create a custom solution specifically for you. Cotta engineers have experience designing specialized speed reducers to meet a variety of requirements and options.
