No more need for toing and froing when you are adjusting the cushioning of pneumatic cylinders. Festo’s self-adjusting cushioning PPS makes commissioning easier and also saves time. It makes it possible to achieve a dynamic but gentle cushioning action into the end positions of cylinders without the need for manual intervention.

Until now, users always needed to adjust the end-position cushioning integrated into cylinders manually, with the risk of slow cycle times or excessive noise generation. Manual adjustment of end-position cushioning also takes time; this makes commissioning a very long drawn-out process in the case of installations with a lot of drives requiring cushioning.
Without any need for manual interventions, self-adjusting cushioning PPS from Festo now ensures an optimum cushioning action every time, even if parameters such as friction and pressure change. It also reduces the acceleration forces acting on components and workpieces. This cuts down wear and minimises time-consuming vibration. What is more, in comparison with shock absorbers, self-adjusting cushioning is less expensive and more robust. This unique cushioning, not offered by any other supplier, is now available with the Festo round cylinder DSNU, of which millions of examples have already been sold.

The DSNU-PPS variant with self-adjusting cushioning described above is not the only member of the DSNU range to offer impressive performance. In addition to the basic, standardised version, DSNU is available with four different mounting options, created by combinations of a total of three different bearing caps and four end caps. This include end caps of block design for direct mounting or with flange threads, end caps with threaded lugs and swivel bearings, with air supply connections that are lateral or in-line with the cylinder axis. The advantages for customers are: no need for costly special solutions, more flexibility during system design and less work when ordering. To ensure that ordering remains transparent and simple, the wide variety of available piston diameters, stroke lengths, functions and variants can be selected with just a single order code. Further variants are available with a through piston rod, heat-resistant seals and clamping units.
The DSNU covers all the applications within the ISO 6432 standard but also goes well beyond this. It will appeal to all users who place the most stringent requirements on round cylinders with regard to quality, a wide choice of variants, availability and price/performance ratio. The well-known long service life of Festo cylinders helps ensure system availability and thus guarantee maximum productivity.
