MAXITORQ^® Fail-Safe industrial clutches and brakes offer a solution to the need for a reliable, spring applied, positive-acting clutch to quickly start a wide range of equipment. Precision designed and manufactured, these units have been thoroughly tested to deliver proven, dependable performance in many diverse applications, from heavy-duty machine tools to fragile assembly and packaging equipment.

Electrically operated, the coil is sealed within a stationary housing which is supported on ball bearings. A powerful electromagnetic force disengages the disc pack unit to provide a low-drag neutral. The internal compressive forces are contained within the clutch and are not transmitted through the bearings. The radial magnetic flux path provides maximum torque throughout the life of the unit. These industrial clutches and brakes provide long service life and can be rebuilt without requiring any special tools.

MAXITORQ^® Spring Applied industrial clutches or brakes feature an adjustable end plate design. In a typical brake installation, the clutch is keyed to a shaft and engages with a stationary cup which is secured to a machined frame or other grounded device. The coil is energized and disengages the armature plate separating the multiple friction discs for release. Actuation of the brake is by means of a limit switch, overload sensor, or similar electric apparatus wired in series with the coil winding. When trouble occurs, the sensing device interrupts the electrical circuit, de-energizing the coil, allowing the coil springs to compress the multiple friction discs, thereby braking the machine to a stop (as a brake) or, by coupling the driving and driven devices (as a clutch).
