Most project delays on high-speed gearboxes trace back to the selection stage. An under-specified unit fails in the first year of service. An over-specified one eats up budget that could have gone somewhere else on the project. The job of the selection engineer is to land in the middle: a gearbox sized exactly for the real load.

Our blog, How to Select a High-Speed Gearbox - Step by Step Guide, walks through the five steps that take you from application to quote-ready spec. It then goes deep on the three numbers that matter most on the data sheet: input power and speed, output torque, and AGMA service factor. https://cotta.com/blog/how-to-select-a-high-speed-gearbox/

A five-step guide to selecting a high-speed gearbox: driver power, output torque, AGMA service factor, and ratio choice.
