WORKING PRINCIPAL: These expand radially inward when pressurized. This constricting tube forces friction shoes against cylinderical drums. This Air pressure pressurizing the tube determines the clutch torque. More is the pressure more is the torque transmited. Centrifugal forces coming into play when rotating, ensures total disengagement as soon as pressure is released.

ADVANTAGES : * Airtube applies force at the maximum radius from axis. * Uniform contact velocity at drum-shoe interface. * Self adjusting, no adjustment 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 360⁰ friction surface.
They are designed to be used boths clutch & brakes in power transmission equipments. They transmit Torque through the side walls of the flexible air tube, using torsional resilient principle. This flexibility also permits minor shaft misalignments.
