Brief History
For more than a century, Cotta has been a leader and driving force in transmission gearboxes. Back in 1906, engineer Charles Cotta introduced his breakthrough constant-mesh shifting transmissions, and soon became a key supplier to the automobile and truck industries.
In the 1940’s, Cotta shifted our focus to industrial products and off-highway / construction specialty vehicles and, in 1960, we added a line of high-speed transmissions. Over the past 50 years, Cotta has diversified into offering other products including speed reducers, speed increasers, hydraulic pumps pump drives and split-shaft PTO’s. Bringing us to today, as Cotta has become the premier, trusted and leading manufacturer of top-quality, precision-engineered transmission products for a wide range of specialized mobile and stationary applications, such as vocational trucks, defense, off-highway, aerospace, heavy industry, well-drilling, mining, marine and more.
Located in a 70,000 square-foot facility in Beloit, Wisconsin, home to our recently-upgraded testing lab, Cotta designs and engineers in accordance with the American Gear Manufacturers Association to ensure our quality – which is monitored systematically, and comprehensively focused on starting at the source to support our “zero defect” policy. After all, it’s a Cotta… it’s your gearbox.

Engineering Manager, Aircraft Appliances and Equipment Limited (AAE)
“We use a Cotta gearbox on our in-house stands used for testing aircraft generators, typically 60kVA to 90kVA. The gearbox has run for over 25 years without a major breakdown. When we’ve ever needed a part or reported a service issue, Cotta is always responsive and meets our need within a week. They have a good, very consistent group of people there. We may need to install another test stand in the future. So, when we need a new high-speed gearbox, Cotta is who we’ll call. AAE has specific requirements for stringent applications, like for running an F-18 aircraft generator at 26,000 RPM, and we can rely on high-quality results from their product.”
