AMCB Eaton Airflex AMCB AccuStop® clutch and brake combinations pack a low-maintenance, high-performance punch. Featuring an air-actuated disc clutch and a spring-applied disc brake, Airflex AMCB AccuStop® units are engineered for small- to medium-tonnage, high-speed, high-cycle punch presses. They deliver high torque and low inertia in a compact design. Features Ductile iron cylinders promote long cycle life under tough industrial conditions Low-inertia components decrease energy loss, optimize cycle times and limit friction material wear Long-life friction material reduces downtime, maintenance and replacement costs Consistent, stable stopping angle decreases the need for adjustments to the press Bolted friction shoes simplify replacement by eliminating the need for disc removal Designed-in safety feature provides a visual signal at the end of friction material life, ensuring that enough torque remains to stop the operation Engineered, self-lubricating composite bushings maintain quiet operation Eaton is ISO 9001 certified and our Airflex AMCB AccuStop™ design conforms to all relevant portions of ANSI B11.1 standard for metal forming presses
