What's the link between an industrial gearbox and an elephant (besides size)? It's the way they can cool themselves! When ordinary cooling isn't enough, SEW-EURODRIVE offers external cooling options to keep the gearbox's oil at the right temperature. Returning today is Austin Burdette, our Industrial Gearing Product Manager, who will take us on a survey trip of industrial gearing external cooling and breather options. And he'll also tell us about elephants!
