The MagnaShear motor brake is a totally enclosed sealed brake for overhead cranes. It is designed for heavy use, hot environments, dirty, and wet applications in steel mills. 

Designed with Oil Shear Technology the MagnaShear Motor Brakes typically mount to the back of a brake motor. They are designed to be a stopping brake, not just a holding brake.

Oil Shear Technology, perfected over 50 years by Force Control Industries, allows the brake to dynamically slip to a stop without wearing friction material, and the fluid circulating through the brake friction stack transfers the heat of engagement to the housing to be cooled. This allows the brake to operate at a consistant torque for many years without adjustment, or maintenance.

They can survive the harsh environments of mining, manufacturing, material handling as well as packaging and food processing with minimal maintenance and no adjustment. The totally enclosed rugged housings keep dirt and moisture out while reducing noise and extracting heat.

Dry friction brakes are typically designed as holding brakes. Using them for dynamic stopping wears friction material away causing constant adjustment and frequent replacement of discs, pads, or shoes.

 Features of a MagnaShear Brake

•     Spring set electrically released - 115 VAC through pulse width modulation for reduced heat and energy cost.

•     Direct acting coil eliminates small linkage parts to corrode, hang up, or fail.

•     Multiple disc design for high thermal capacity and up to 80% lower rotating inertia

•     Oil Shear Technology for smooth cushioned stops, minimal wear, no adjustment required, superior heat dissipation and consistent accurate stopping

•     Up to 10 times longer life, Up to 50% Lower Cost per IndexMagnaShear MSB8 Low Temperature Brake Motor. Click to Download Catalog

•     Heavy duty totally enclosed sealed housing for protection in severe dusty, dirty, or wet applications.

•     Clamped split quill option for severe duty applications provides superior 360º shaft connection minimizing key and keyway problems.

•     Quick mount design installs in one piece. No assembling parts on the motor, small parts to drop, covers to remove for adjustment.

•     Optional wash-down and marine duty designs

•     Custom flange designs for IEC, reducer mounting, or old crane retrofits.

•     Manual release, optional release indicator switch, heater, encoder shaft

•     Simple transformers used for alternate voltages.
