The MagnaShear motor brake from Force Control Industries employs oil shear technology, providing longer service life even in demanding applications like the frequent start/stop cycles seen on conveyors, cranes 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 which is the most common problem in dry braking systems. Elimination of the wear significantly increases service life and virtually eliminates adjustment that also elongates maintenance intervals.
MagnaShear motor brakes are ideal for applications where the motor is reversed each cycle such as loader/unloader conveyors, rail car spotters and dumpers, ship and rail car loading conveyors, trippers and pallet return conveyors. They are also well suited for cranes, winches and other material handling equipment.
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, forest products manufacturing, and more.
Unlike dry brakes, oil shear technology includes a layer of automatic transmission fluid between the brake disc and the drive plate. As the fluid is compressed, the fluid molecules shear – thus imparting torque to the other side. This torque transmission causes the stationary surface to turn, bringing it up to the same relative speed as the moving surface. Since most of the work is done by the fluid particles in shear, wear is virtually eliminated. Elimination of wear also eliminates the need for adjustments which are common for dry braking systems.
In addition to transmitting torque, a patented fluid recirculation system helps to dissipate heat which is the major problem with traditional dry brakes. Along with heat removal and torque transmission, the fluid serves to continually lubricate all components of the oil shear brake, elongating their service life.
MagnaShear motor brakes are enclosed from outside contaminants, with seal integrity for harsh and washdown environments. A modular design and assembly allows for ease of servicing and maintenance.
