Description
589 N on the advance stroke and 495 N on return at 6 bar, plus a 80 mm stroke: the Festo DGST-25-80-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
- Repetition accuracy ≤ 0.3 mm for reproducible end positions
- Ball cage guide for transverse forces up to 1030 N and torques Mx 14 Nm, My 11 Nm, Mz 11 Nm
- Theoretical force at 6 bar: 589 N advance, 495 N return
- 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.
