Rotork plc Datasheets for Gearboxes and Gearheads
Gearboxes and gearheads, also called gear reducers or speed reducers, are power transmission devices that use a gear arrangement in an enclosed housing to transfer energy, increase torque and reduce speed from one device to another. Gearboxes may also be referred to as gear reducers or speed reducers.
