Force Control Industries MagnaShear™ maintenance-free, no-adjustment motor brakes virtually eliminate motor brake downtime, and since the best kind of maintenance is no maintenance, they can also help to alleviate problems associated with worker shortages.
With no adjustment or maintenance required, save for an annual oil change, these dependable motor brakes allow maintenance personnel to be tasked with other projects, thus accomplishing more work with fewer employees.
The MagnaShear™ motor brake employs oil shear technology, providing longer service life in demanding applications like the frequent start/stop cycles seen on cranes, hoists, winches, conveyors, palletizers, and other 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 which is the most common problem in dry braking systems.
Elimination of the wear significantly increases service life and virtually eliminates adjustment which also elongates maintenance intervals. They are ideal for applications where the motor is reversed each cycle such as rail car spotters and dumpers, ship and rail car loading conveyors, trippers and pallet return conveyors.
The oil shear technology also provides a smooth "cushioned" stop which reduces shock to the drive system, further extending service life of downstream components.
The totally enclosed MagnaShear™ brakes are impervious to moisture, dirt and dust that is common in concrete block plants as well as asphalt shingle manufacturing, coal, bulk materials handling, and more.
Suitable for a Wide Range of Motor Sizes
These proven motor brakes are available to accommodate a wide range of applications. Spring set torque ratings from 3 to 1250 foot-pounds are available. MagnaShear™ motor brakes are available in multiple torques for the same motor frame.
MagnaShear™ motor brakes feature "quick mount" features for quick and easy mounting to drive motors in NEMA frame sizes 56 to 449. They are shipped ready to install, with no assembly or adjustments required.
They are also available pre-mounted on a motor for severe duty applications. MagnaShear™ motor brakes 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.
