Description
295 N advancing force from a flat profile: the Festo DZF-25-50-A-P-A works with an equivalent piston Ø of 25 mm and 50 mm stroke. The oval piston keeps the piston rod aligned.
Benefits
- Theoretical force at 6 bar: 295 N advance, 247 N return
- Oval piston prevents rotation: the piston rod turns by no more than 1° and takes up to 0.5 Nm of torque
- Elastic cushioning rings at both ends (P)
- Air connection M5
- Prepared for proximity switches to sense the end positions
- Operating pressure 1 to 10 bar
Applications
Typical tasks for the DZF-25-50-A-P-A are clamping, stopping and ejecting in fixtures and assembly stations with no room for a round cylinder. Its 50 mm stroke covers short travel.
