Flat cylinder, double-acting, Ø 40 mm stroke 250 mm DZF-40-250-A-P-A - Festo 161287
Rotation-proof without an external guide thanks to the oval piston, 754 N advancing force at 6 bar and 250 mm stroke. The Festo DZF-40-250-A-P-A fits where a round cylinder takes up too much space.

Description
754 N advancing force from a flat profile: the Festo DZF-40-250-A-P-A works with an equivalent piston Ø of 40 mm and 250 mm stroke. The oval piston keeps the piston rod aligned.
Benefits
- Oval piston prevents rotation: the piston rod turns by no more than 0.6° and takes up to 1 Nm of torque
- Theoretical force at 6 bar: 754 N advance, 633 N return
- Elastic cushioning rings at both ends (P)
- Operating pressure 1 to 10 bar
- Air connection G1/8
- Prepared for proximity switches to sense the end positions
Applications
In tool and fixture building the DZF-40-250-A-P-A handles clamping and pushing with 250 mm stroke, even with several cylinders mounted close together.
