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.
