Double-acting mini slide piston Ø 25 mm stroke 20 mm DGST-25-20-E1A - Festo 8078873
For guided strokes of 20 mm, the Festo DGST-25-20-E1A produces 589 N forward and 495 N on return at 6 bar. The ball cage guide absorbs transverse forces up to 1460 N without loading the piston rod. The slide reaches its end positions with a repetition accuracy of ≤ 0.3 mm.

Description
589 N on the advance stroke and 495 N on return at 6 bar, plus a 20 mm stroke: the Festo DGST-25-20-E1A is a mini slide for handling axes in tight spaces. The twin piston design doubles the effective piston area compared with a single piston of the same diameter.
Benefits
- Theoretical force at 6 bar: 589 N advance, 495 N return
- Repetition accuracy ≤ 0.3 mm for reproducible end positions
- Ball cage guide for transverse forces up to 1460 N and torques Mx 16 Nm, My 16 Nm, Mz 16 Nm
- Travel speed up to 0.5 m/s
- End position cushioning: elastomer cushioning at both ends, permissible impact energy 0.3 J
Applications
The slide is used in placement, assembly and packaging systems where short strokes with high guide accuracy are needed. Mounting with through-hole, any mounting position. End positions can be sensed with proximity switches.
