Festo ADN-PPS pneumatic compact drive

Festo has released a variant of its ADN compact drive with PPS pneumatic end-position cushioning. The design minimises end-position impact while at the same time improving reliability.

The self-adjusting, end-position cushioning reduces vibration and therefore enables high speed and shorter machine cycles. The ADN with PPS reduces costs and errors. The self-adjusting pneumatic cushioning of the ADN-PPS never needs to be adjusted, which means that sources of error such as incorrect adjustment or accidental re-adjustment are no longer an issue. The PPS cushioning efficiently converts energy and effectively brakes loads, and it can adjust to changing load and speed.

Typically users have to manually adjust the integrated pneumatic end-position cushioning in the cylinder - at the expense of cycle times and noise generation. Manual cushioning adjustment is also time-consuming, prolonging the commissioning of systems when there are many drives to be cushioned. PPS self-adjusting cushioning ensures optimum cushioning performance at all times without the need for any manual intervention.
