CBC Clutch/Brake Combination CBC Clutch/Brake Combination Section F The Airflex® CBC clutch/brake combination consists of an air-actuated disc clutch and a spring-applied disc brake. Its compact design combined with its high thermal capacity and low air consumption makes it ideal for high speed, high cyclic, heavy-duty industrial applications. The CBC hub is pressed on and keyed to the driven shaft. The clutch disc is fastened to the driving member (a flywheel in most applications). The brake disc is reacted to the machine. Three different means of disc attachment results in five possible...
