Description
153 N advancing force from a flat profile: the Festo DZF-18-25-A-P-A works with an equivalent piston Ø of 18 mm and 25 mm stroke. The oval piston keeps the piston rod aligned.
Benefits
- Theoretical force at 6 bar: 153 N advance, 123 N return
- Oval piston prevents rotation: the piston rod turns by no more than 1.2° and takes up to 0.2 Nm of torque
- Elastic cushioning rings at both ends (P)
- Air connection M5
- Operating pressure 1 to 10 bar
- Prepared for proximity switches to sense the end positions
Applications
Typical tasks for the DZF-18-25-A-P-A are clamping, stopping and ejecting in fixtures and assembly stations with no room for a round cylinder. Its 25 mm stroke covers short travel.
