BCD Series (Multi-Friction Facing Water-Cooled Air Brakes)

Torque range: 180~4700Nm
Multi-Friction Facing Water-Cooled Air Brakes have high heat capacity and realize a wide range of torque controls, which is three (3) times wider than standard brake.
Typical Applications: Winders, Slitters, Cutters, Coaters, Metal Working Machines, Thread Working Machines.

Feature:

• Double Piston Provides Wider Range of Torque Controls
  The attachment of two (2) pistons allows wider range of torque control. At high torque, the two pistons jointly operate, and at low to middle torque, one (1) piston operates independently. As a result, the wide torque operation range (1:60) is realized that would normally take three (3) brakes.
• Large Braking Workload
  The high heat conductive alloy disc is employed, which effectively absorbs generated heat, and thus has realized the long–lasting usage even under severe conditions such as continuous slip.

• Compact Design and High Torque
  The placement of multiple friction facings can produce twice and quadruple torque of the single friction facing while keeping the original diameter.
• Long-Life and Stable Torque
  The friction facing of BCD Series Brakes employs our originally developed non-asbestos material, which matches well with the special alloy discs.
  The life of the friction facing is 5-10 times longer than the other materials. The generated torque is always stable for use of long continuous slipping.
• Effective Rustproof
  The water line is cupper-plated for effective rustproof.

BCD Series Brakes contain the large and small pistons aligned concentrically on one side. The center plate with friction facing, which rotates with an axis, is placed between the piston-pressurized water-jacket and the fixed water jacket. Each jacket, equipped with high heat conductive special alloy disc, cools the brake with cooling water.
BCD100, BCD200 and BCD300 Series Brakes use 2,4,6 friction facings, respectively.
When air pressure is applied, the piston pushes water jacket. Then, the center plate with a friction facing is pushed against and makes a contact with the fixed water jacket. Air is released by return spring.
The small and large pistons can be operated jointly or independently.
