The MagnaShear motor brake from Force Control Industries employ oil shear technology, providing longer service life in applications like the frequent start/stop cycles seen on conveyors, cranes, hoists, winches, and other material handling equipment.

Proven oil shear technology transmits torque between lubricated surfaces, thereby eliminating wear on friction surfaces. A patented fluid recirculation system dissipates heat, eliminating heat build-up.

The oil shear technology provides a “cushioned” stop, which reduces shock to the drive system, further extending service life of downstream components.

The enclosed MagnaShear brakes are impervious to moisture, dirt and dust that is common in bulk materials handling facilities.


Spring set torque ratings from 3 to 1250 foot-pounds are available. MagnaShear motor brakes can be sized to the correct torque independent of the motor frame size or horsepower.

MagnaShear motor brakes feature “quick mount” for quick and easy mounting to drive motors in NEMA frame sizes 56 to 449. They are available pre-mounted on a motor for severe duty applications.

They can be furnished to fit a NEMA or IEC frame motor, as a complete motor and brake assembly, or to mount on a machine frame or other special mounting configuration.
