Festo
14921
Standard cylinder DNU-50- -PPV-A-S6
The Festo 14921 is a double-acting industrial component featuring a 50 mm piston diameter, an M16x1,5 piston rod thread with a male end, and a variable stroke ranging from 1 to 2,000 mm. Built with a piston and piston rod design conforming to ISO 6431, this unit operates at pressures between 0.5 and 12 bar using dried compressed air and incorporates adjustable pneumatic cushioning at both ends with heat-resistant seals rated up to 120 °C. It delivers a theoretical force of 1,131 N on the advance stroke and 924 N on the return stroke at 6 bar, while supporting position detection via proximity sensors in any assembly position.
