Festo
1646820
ISO cylinder DSBG-100-125-PPSA-N3
The Festo 1646820 is a double-acting industrial component featuring a 100 mm piston diameter, a 125 mm stroke, and an M20x1.5 external piston rod thread conforming to ISO 15552. It operates at pressures from 0.04 MPa to 1.2 MPa (0.4 bar to 12 bar) using compressed air according to ISO 8573-1:2010 [7:4:4], delivering a theoretical retracting force of 4418 N at 6 bar while utilizing self-adjusting pneumatic end-position cushioning with a 31 mm cushioning length and 2.5 J end-position impact energy. Configured with a tie-rod structural design and a single-end piston rod for mounting in any position, the unit includes position sensing via proximity switch, moderate corrosion resistance (CRC 2), and an ambient temperature range of -20 °C to 80 °C.

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.
