The coupler brake 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. The coupler brakes can be used in virtually any application in which common electrically released motor brakes are used, including palletizers, conveyors, hoists, loaders, unloaders, and many others. The 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. With the Oil Shear Technology the brakes do not need maintenance, adjustment and last up to 10 times longer than standard electric motor brakes, according to the manufacturer. The spring set coupler brakes come in many sizes and torques for motor frame sizes 56 to 320 and torque ranging from 6 Lb. Ft. to 450 Lb. Ft. They can be used horizontally or vertically, and require a very small amount of air up to 80 PSI. The brakes are available in other configurations such as brake motors, through shaft, and flange mounted. They can also be spring set, air release, or air set, spring release. Hydraulic actuation is available for applications where air is not an option.
