Double-acting mini slide piston Ø 20 mm stroke 20 mm DGST-20-20-E1A - Festo 8078863
For guided strokes of 20 mm, the Festo DGST-20-20-E1A produces 377 N forward and 317 N on return at 6 bar. The ball cage guide takes transverse forces up to 1270 N and torques up to 14 Nm. The slide reaches its end positions with a repetition accuracy of ≤ 0.3 mm.

Description
Where small loads have to be moved precisely along a guide, the mini slide DGST-20-20-E1A is the right unit: 20 mm stroke, piston Ø 20 mm and 377 N advance force at 6 bar, combined with a ball cage guide. The twin piston design doubles the effective piston area compared with a single piston of the same diameter.
Benefits
- Theoretical force at 6 bar: 377 N advance, 317 N return
- Travel speed up to 0.5 m/s
- Ball cage guide for transverse forces up to 1270 N and torques Mx 13 Nm, My 14 Nm, Mz 14 Nm
- End position cushioning: elastomer cushioning at both ends, permissible impact energy 0.2 J
- Repetition accuracy ≤ 0.3 mm for reproducible end positions
Applications
The DGST-20-20-E1A works as a lifting or transverse axis in handling systems, also in combination with grippers. Port G1/8, operation at 1 to 8 bar and -10 to 60 °C ambient temperature. End positions can be sensed with proximity switches.
