Oil shear coupler brake

Posistop oil shear coupler brake, ideal replacement for electric brakes often found mounted on the back of a special brake motor, mounts to the working end of a standard C-face motor eliminating the need for a special brake motor. This means the motor can be used for non-brake applications as well, thus reducing motor inventory. This also may allow use of a fan-cooled motor, which is sometimes not possible with brake mounted on the fan end.

The coupler brakes can be used in virtually any application in which common electrically released motor brakes are used, including palletizers, conveyors, hoists, loaders and unloaders. They can be used on the working end because they are not frequently removed or opened up for maintenance and adjustment. With oil shear technology, the brake life is often as long as the motor service life.


These brakes feature Teflon liners on all piston-sealing areas for a smooth response and long service life. This also eliminates o-ring breakage. Bearings are oil lubricated. Solid cast iron or aluminum totally enclosed housings protect the brake from adverse environments including dust, dirt and moisture.

The spring set Posistop coupler brakes come in many sizes and torques for motor frame sizes 56 to 320, and torque ranging from 6 to 450 lb.-ft. They can be used horizontally or vertically, and require a small amount of air up to 80 psi. Brakes are available in other configurations such as brake motors, through shaft and flange mounted. They also can be spring set, air release or air set/spring release. Hydraulic actuation is available for applications where air is not an option. Force Control Industries; www.forcecontrol.com
