Brakes and Clutches

Sjogren Magnetic Tensioning Brakes and Clutches offer a unique solution to managing torque or tension control problems. These devices operate on the powerful principles of magnetism, delivering constant or variable torque. They are small, extremely rugged and simple to mount and adjust. They require no external power—no wiring, no electronic components—and are virtually maintenance free. There are no “mechanical wear” parts (except for ball bearings).
