Custom Brake Solutions

From slight modifications of our catalog models to completely clean sheet creations, Mach III specializes in creating custom brake designs. Through collaboration with our engineers, clients receive precise solutions for their new machine design or retrofit application. Below are examples of some of the custom friction brakes Mach III has manufactured.

Power Drill Torque Couplings

PREVENT DAMAGE AND DISCOMFORT Mach III’s torque limiting coupling has been used for decades to turn heavy-duty power drills such as the Milwaukee Super Hole Shooter Drill and Unitec ETE 32 into efficient tools for opening and closing gate valves, butterfly valves, ball valves, plug valves, mud valves, sluice gates, slide gates and other rotary…
