A powerful drive calls for cushioning that extends the operating life of machines. Festo has addressed this need with a variant of the compact drive ADN with pneumatic end-position cushioning PPS. The design minimises end-position impacts while at the same time improving reliability thanks to the self-adjusting cushioning.
The self-adjusting end-position cushioning reduces vibrations and thus enables high speeds and short 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. It adjusts perfectly to load and speed, even when these change
Up to now, users had 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 with lots of drives to be cushioned. PPS self-adjusting cushioning ensures optimum cushioning performance at all times without the need for any manual intervention
