Ross Gear and Tool MG141210AAAB Hydraulic Torqmotor

Ross Gear MG141210AAAB TRW Hydraulic Torqmotor is a hydraulic torque motor designed for high-torque, low-speed output in industrial hydraulic drive systems, featuring a 1-inch output shaft and 3/4-inch NPT ports for fluid input and return. Identified by part number MG141210AAAB and associated with the TRW line from the Ross Gear Division, this unit carries Spec# 061 89 C and is listed as a used torque motor in dealer inventories. The vendor notes this as a used TRW Ross torqmotor, which is typical of Ross/TRW torque-motor products designed to convert hydraulic pressure into slow, high-torque shaft rotation. Torqmotors such as this unit generally derive torque through internal gearing in a positive-displacement hydraulic motor, multiplying displacement to deliver high torque at low shaft speed, a hallmark that makes them suitable for hydraulic drives requiring robust torque at standstill.
