Adjustable cushioning and "Ideal Cushioning"

Save costs and energy with the right adjustment

Good pneumatic cushioning is critical for strong cylinder performance. With its numerous advancements over the years, adjustable cushioning from AVENTICS is a leading product in the market. 

Basically, there are two different types of pneumatic cushioning: preset cushioning and adjustable cushioning. With preset cushioning, a standard value is assumed. Adjustable cushioning can be tailored to specific applications and is therefore more efficient. Uncushioned cylinders strain transported workpieces, shorten the service life of the module, and generate vibrations within the entire machine.

More efficient – and faster

Adjustable cushioning not only saves energy, but also reduces cycle times. Only a few turns of the screw are sufficient to ideally adjust the cushioning to the workpiece weight and the dynamics of the movement.

Arguments in favor of adjustable cushioning

• Productivity – higher cycle times thanks to greater speed in reaching the end position
• Reduced energy consumption – smaller cylinders with the same cushioning performance
• Smooth-running – fewer vibrations – less noise
• Cost savings – possible to select smaller and more economical cylinders, valves, and peripherals

AVENTICS “Ideal Cushioning”

AVENTICS “Ideal Cushioning” is a method to optimize cushioning leading to reduced shock/vibration, reduced noise and reduced cycle times. “Ideal Cushioning” means that the direction of travel of the piston is the same throughout the entire cushioning sequence (i.e. no piston bounce) and that its velocity is exactly zero when it reaches the end of its travel. The sound of end cover contact is negligible and the total cycle time is optimized. Thus, properly adjusted pneumatic cushioning has positive effects on the working environment and on the total working cycle time. Many OEMs and end users have used this method to greatly increase machinery productivity.

It should be noted that cylinders capable of achieving true ‘”Ideal Cushioning” have both precision pneumatic cushion adjustment and elastic elements for impact cushioning. Many AVENTICS cylinders including RTC rodless, and PRA/TRB/ICL ISO 15552 cylinders are “Ideal Cushioning” capable.
