This type is generally used in clutch & Brake application where large inertia loads are involved resulting in loss of torque
& operating life. In this torque is transmitted by steel torque bars rather than the side walls of activating air tube. I this triction shoes & side place have large air passages which allows air to flow through the clutch. This type of clutch can take substantial amount of slip.
These clutches/Brakes elements are also available which available in split design in two halves, to cut maintenance time.
