Double-acting mini slide piston Ø 12 mm stroke 20 mm DGST-12-20-E1A - Festo 8078847
With a 20 mm stroke and 136 N theoretical force at 6 bar, the DGST-12-20-E1A handles short, guided linear movements. The recirculating ball bearing guide absorbs transverse forces up to 520 N without loading the piston rod. The slide reaches its end positions with a repetition accuracy of ≤ 0.3 mm.

Description
The mini slide DGST-12-20-E1A makes a separate guide on the cylinder unnecessary. The recirculating ball bearing guide is built in, the stroke is 20 mm with a 12 mm piston. Inside the housing, two pistons of 12 mm diameter each act in parallel on the yoke.
Benefits
- Repetition accuracy ≤ 0.3 mm for reproducible end positions
- Travel speed up to 0.5 m/s
- End position cushioning: elastomer cushioning at both ends, permissible impact energy 0.07 J
- Recirculating ball bearing guide for transverse forces up to 520 N and torques Mx 4.2 Nm, My 4.2 Nm, Mz 4.2 Nm
- Theoretical force at 6 bar: 136 N advance, 102 N return
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.
