Magnetic Brakes & Clutches
HYSTERESIS TENSIONING BRAKES
Protect the drive train of your winding, spooling, or wrapping operation from overload by providing constant torque regardless of rotation speed. Sjogren’s tensioning brakes require no external power source, making them easy to incorporate into the OEM process or as a replacement component.
HYSTERESIS TENSIONING FEED-BACK BRAKES
Sjogren’s Hysteresis Tensioning Feed-Back Brakes are the easiest way to provide constant tension during pay-off operations, without requiring any external power source or operator adjustment. The feedback arm automatically adjusts the torque throughout spool pay-off.
EDDY CURRENT TENSIONING CLUTCH
An economical and low-maintenance approach to solving uneven torque problems in the wind-up operations of wire, plastic film, tapes, or textiles. Sjogren’s tensioning clutches require no external power source, have virtually no wear parts, and are easily adjusted to a variety of loads/conditions.
