The Dodge Motorized Torque-Arm II (MTA) is a shaft-mount reducer with a right-angle NEMA motor input, built for belt conveyors and other shaft-mounted drives where a V-belt drive is not wanted. It mounts on the driven shaft with twin-tapered bushings, uses a harsh-duty metal-shielded seal system, and is factory-ready for Dodge condition-monitoring sensors.
