Altra Industrial Motion



Altra Industrial Motion is an American manufacturer of mechanical power transmission products – brakes, clutches, couplings, and the like. The company is headquartered in Braintree, Massachusetts.

While the products sound automotive to the layman, in fact most Altra products are used on industrial machinery, such as fail-safe brakes for elevators and forklifts, gearboxes on conveyors, heavy duty brakes on mining equipment, clutches for beverage capping equipment, etc.
