MAGNASHEAR Brakes Approved by CSA For Hazardous Duty Applications

Force Control Industries' MAGNASHEAR hazardous duty (MHD) motor brakes are now CSA approved for hazardous duty applications in North America. With Oil Shear Technology, MHD brakes are available in torque capacities ranging from 3 to 1250 lb-ft.

Designed for fast installation, MAGNASHEAR brakes feature a "Quick Mount" design for direct mounting to standard NEMA 56C through 449TC motors. Fully enclosed and sealed against dirt, moisture, and other contaminants, they are well suited for severe-duty and washdown environments.

Typical applications include where explosive dust us present, as well as cranes, hoists, winches, ship and railcar loading and unloading conveyors, tipper cars, and other equipment requiring frequent stopping or accurate positioning.

Oil Shear Technology

Unlike conventional dry brakes, MAGNASHEAR brakes transmit torque through a thin film of automatic transmission fluid between the friction discs and drive plates. As the brake engages, the fluid molecules shear, smoothly transmitting torque while bringing rotating surfaces to synchronous speed. Because torque is transmitted through the fluid rather than direct frictional contact, wear on the friction surfaces is minimized, resulting in dramatically longer service life without the need for periodic air-gap adjustments.

A patented fluid recirculation system continuously removes heat from the friction stack, preventing the
