With 60 years of proven dependability and more than 1.8 million units in service throughout the world, Dodge Torque-Arm speed reducers are the standard of the industry and the benchmark to which others are compared. Responding to overwhelming customer demand, we have now introduced a line of HEAVY DUTY right angle beltless Torque-Arm reducers for customers who need the power and performance of a truly rugged gearbox for more demanding applications. The Dodge MTA gear reducer features the patented Dodge twin-tapered bushing system that makes it easy to mount and dismount with no corrosion or shaft damage.  Also available as a motorized screw conveyor drive with an adapter and drive shaft. Designed to perform in harsh conditions, the MTA has a patented premium sealing system to ensure maximum up-time with less maintenance.
