Cotta. It’s Your Gearbox.

Kevin Loffredo, Senior Engineer and Partner at Staley Co.

“Staley Co. uses Cotta high-speed gearboxes for some of our most difficult and demanding applications for aviation component test equipment. We have successfully integrated Cotta gearboxes in test stands ranging from 25 to 300 HP and 20,000 to 60,000 RPM. As a custom integrator of components from many manufactures, large and small, Cotta ranks up there as one of the best. We have worked closely with their engineering team time and time again, particularly on unique challenges for mounting a particular aircraft component on test. We have found the team at Cotta to be extremely knowledgeable, professional and, in a word, ‘speaking our language.’

Beyond the engineering and initial purchase, after sales support and product reliability have been tremendous. Over 30 plus years, we have deployed dozens and dozens of Cotta gearboxes without issue. In several cases, with the help of Cotta engineers, we have even been able to retrofit 25 to 30-year old boxes with different gear sets for a different speed range application. In short, when it comes time to look for a high-speed gearbox, we know who to call.”

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.”
