Miki Pulley Brake Models Designed for Overhead Garage Door Applications

Commercial garage doors range in many sizes and configurations requiring a “just right” model and size brake for reliable automatic operation. Depending on the design and size of the overhead door and placement of the brake, a variety of brake models and sizes offer solutions from the Miki Pulley brake lineup. 

For lighter and faster operating garage doors, the smaller Miki Pulley BXW model is an ideal choice. It performs as a stopping and holding brake that performs efficiently when placed between a drive motor and gearbox.

For heavier, slower-opening doors, a large Miki Pulley BXR Brake model is effective for opening and holding the door open efficiently for worker safety.

Both the BXW and BXR brakes are spring actuated power-off brakes. This means when voltage is applied (while door is opening or closing) the brake is dis-engaged allowing free rotation. When the door is at its open or closed position and no voltage is flowing, the brake’s compression springs within the stator housing press the armature plate against the rotor disc   halting and holding all door movement. This ensures safe door operation while the brake consumes electric power only when the door is in motion.

An important operating feature: Miki Pulley Brakes are “all weather” brakes with ambient operating temperature of 14°F—104°F (-10°C to 40°C).
