We manufacture high quality pneumatic multi-disc clutches and brakes. Made from the best raw materials, our clutch and brakes are superior in design. The salient features of our clutches and brakes are:

Working
Our multi-disc Clutch/ Brakes operate by actuating the piston using 'U' seals by admitting pneumatic pressure to the unit cylinder. The moving Piston produces axial pressure on the Clutch Disc on release of air pressure Piston is pushed back by multiple return springs. In Spring applied brake discs is produced by multiple springs and brake is released by compressed air pushing back the piston.

Torque Variations
The clutch units have a torque capacity directly proportional to effective air pressure in the clutch Cylinder. The maximum operating air pressure allowed is 6.0 Bar.

We also have a spring applied brake units torque capacity is directly proportional to spring pressure on the Brake units Torque Capacity is directly proportional to spring pressure on the brake disc. The sir pressure can be released by varying the spring complement.

We fabricate pneumatic clutches & brakes for specialized industrial purposes. We use the best in raw materials that are procured from reputed manufacturers.

Working
Our pneumatic industrial clutch and brakes are tyre-like fabric reinforced rubber Air Tubes molded inside the steel rim. Ruggedly built these expand radially inwards when pressurized. This constricting tube forces friction shoes against cylindrical drums. This Air pressure pressurizing the tube determines the clutch torque. More is the pressure, more is the torque transmitted. Centrifugal forces coming into play when rotating, ensures total disengagement as soon as pressure is released.

Advantages

• Air tube applies force at the maximum radius from axis
• Uniform contact velocity at drum-shoe interface
• Self adjusting, no adjusting for wear
• It requires no lubrication
• Centrifugal forces assist clutch disengagements
• It operates in any plane
• Highly efficient, rugged & reliable.
• Flexible rubber reinforced air tube dampen the shocks & compensate for slight misalignment.
• Full 360 friction surface.

Salient features of our Pneumatic combination clutches and brakes are:

Working
Our Pneumatic Combination Clutch/Brake comprises of a clutch & spring applied Disc Brake which is air actuated. The Clutch/ Brakes are intricately designed. It has the twin attributes of high thermal capacity & low air consumption which makes it ideal for high speed, high cyclic, heavy-duty industrial application. When cylinder is pressurized, the piston clamps the clutch disc to the hub which transmits the torque to the shaft. When cylinder exhausts, the springs moves the piston in the opposite direction clamping the brake disc & stopping the shaft. The totally cancels out overlap of clutch & Brakes.

Mounting
The clutch/ brake are housed in a hub which is pressed & keyed to the driven shaft. These plates can be suspended on twelve pins & guide bushes or on two coaxial or non-coaxial bolts.

Applications

• Power Presses
• Press Brakes
• Guillotines
• Printing Machines
• Wood Working Machines

Advantages

• High Thermal Capacity
• Stable Coefficient of friction
• Low Air Consumption
• Low Operating & Maintenance Cost
• Easy removal of worn out linings

The features of our heavy duty pneumatic industrial clutches & brakes are:

Torque Variations
The air is pressurized in the clutch / brake is compressed at 5.0 bar (75 psi) is applied to the rubber tube which expand & forces the friction blocks to the friction drum, transmitting the torque. When air is released to the atmosphere, release springs and centrifugal action results in positive disengagement of the clutch/brakes.

Advantages

• The torque is transmitted by steel torque bars not by the side walls of the air tube, thereby chances of air tube leakage due to slip or overload are eliminated.
• Better suitable for heavy starting loads where slipping can be prolonged, it can also be used in slipping application like rewinders and tension brakes. Positive disengagement as release springs are used in this design.Self adjusting, no adjustment required during full life of the clutch. Requires no lubrication and operates in any plane.
