Festo
35521
Standard cylinder DNGZK-50- -PPV-A-S8
The Festo 35521 is a double-acting industrial component featuring a 50 mm piston diameter, an M16x1,5 piston-rod end with a male thread, and a stroke range from 1 to 2,000 mm based on ISO 15552. Operating at pressures between 0.6 and 12 bar using compressed air in accordance with ISO 8573-1:2010 [7:4:4], this piston and piston rod assembly delivers a theoretical force of 1,178 N on the advance stroke and 990 N on the return stroke at 6 bar. It incorporates adjustable pneumatic cushioning at both ends (PPV) with a 23 mm cushioning length, position detection for proximity sensors, and a corrosion resistance class of CRC 2 with KBK3 heavy-duty corrosion protection on external surfaces.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
