Flat cylinder, double-acting, Ø 18 mm stroke 125 mm DZF-18-125-A-P-A - Festo 161243
Rotation-proof without an external guide thanks to the oval piston, 153 N advancing force at 6 bar and 125 mm stroke. The Festo DZF-18-125-A-P-A fits where a round cylinder takes up too much space.

Description
The flat cylinder DZF-18-125-A-P-A fits 125 mm of stroke into a flat housing and pushes with 153 N at 6 bar. Its oval piston limits piston rod rotation to 1.2°, so a separate guide is often unnecessary.
Benefits
- Oval piston prevents rotation: the piston rod turns by no more than 1.2° and takes up to 0.2 Nm of torque
- Theoretical force at 6 bar: 153 N advance, 123 N return
- Elastic cushioning rings at both ends (P)
- Operating pressure 1 to 10 bar
- Air connection M5
- Prepared for proximity switches to sense the end positions
Applications
The DZF-18-125-A-P-A is used in fixture building, assembly and test stations, for instance to clamp workpieces or as a stop with 125 mm stroke.
