Cotta’s high-speed gearboxes are built to provide many years of service, which is a reason why some of the largest OEM companies in the world have come to Cotta for custom built gearbox solutions.  In addition to designing high-speed gearboxes for speed management in non-aviation and industrial applications, where highly-specialized, powerful and reliable solutions are needed, Cotta has also designed numerous gearboxes for R&D and production test stand applications for automotive, aerospace, and industrial components.

Cotta’s engineering team designed this high-speed gearbox that will be used in a test stand for an aerospace application.  After the assembly process is completed, additional quality checks will be made on the gearbox as it goes through testing in Cotta’s high-speed programmable test cell.  See gearbox specifications below:
