High-Speed Gearbox SN2285 for Aerospace Product Testing

Cotta recently designed and built this new High-Speed Gearbox Model SN2285 for testing use on aerospace products by a customer in the Indianapolis, IN area. Our Model SN2285 is a foot-mounted, single increasing stage, single output, high-speed gearbox that is designed for test stand use. This model comes standard with a double-keyed stub input shaft and an aerospace output mounting pad. The input can be driven clockwise or counterclockwise, with the output rotating in opposite direction to the input. Due to its compact size, this gearbox is designed to operate with a remote lube supply.
