Magnashear hazardous-duty (MHD) motor brakes are now CSA-approved for hazardous-duty applications in North America. Featuring Oil Shear Technology, MHD brakes are available in torque capacities ranging from 3 to 1250 lb-ft and deliver exceptionally long service life with virtually no maintenance and zero adjustment. Designed for fast installation, Magnashear brakes feature a “Quick Mount” design for direct mounting to standard NEMA 56C through 449TC motors. Unlike conventional dry brakes, Magnashear brakes transmit torque through a thin film of automatic transmission fluid between the friction discs and drive plates. Standard models are available for direct mounting on NEMA 56C through 449TC motor frames, but metric and custom mounting provisions are available upon request.
