Pneumatic Cushion for CNC Punch Presses

The AIRSUSTECH F-240-4 air bellow is a quadruple-convoluted rubber air spring specifically engineered for CNC punch and stamping presses, providing superior pneumatic cushioning during high-speed metal punching operations
Effectively absorbs mechanical shock, controls vibration, and delivers smooth support as loads change throughout the punching cycle
Compresses during the downward stroke to store energy, then facilitates rapid press ram return for optimal operational efficiency
Adjustable internal air pressure (up to 0.88 MPa) allows customization of load capacity and cushioning effects to match specific operating requirements
Maintenance-free design with no internal sliding metal parts, eliminating friction concerns and lubrication requirements
Compact installation height combined with substantial stroke length makes it ideal for space-constrained punch press applications
Adaptable force characteristics enable accommodation of different die weights and material thicknesses through compressed air pressure regulation
