Name: Festo 534769 Guided drive DFM-50- -B
Brand: Festo

Guided drive DFM-50- -B

This Festo industrial component features a 50 mm piston diameter, a 25 mm to 400 mm stroke, and a double-acting yoke drive unit operating mode with elastic cushioning, adjustable pneumatic cushioning, or a soft characteristic curve pneumatic shock absorber at both ends. It includes a plain-bearing or recirculating ball bearing guide, position sensing via proximity switch, and ATEX and UKCA certifications for Zone 1 and Zone 2 gas explosive environments within a temperature range of -20°C to +70°C. Operating between 1 bar and 10 bar using compressed air, the structural design accommodates any mounting position and offers options for heat-resistant seals up to 120°C and oil lubrication.

Why 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.
