Description
Where small loads have to be moved precisely along a guide, the mini slide DGST-20-40-Y12A is the right unit: 40 mm stroke, piston Ø 20 mm and 377 N advance force at 6 bar, combined with a ball cage guide. Two pistons working in parallel drive the yoke.
Benefits
- Repetition accuracy ≤ 0.02 mm for reproducible end positions
- End position range adjustable over 27 mm at the front and 26.5 mm at the rear
- Travel speed up to 0.5 m/s
- End position cushioning: external hydraulic cushioning, permissible impact energy 1.9 J
- Theoretical force at 6 bar: 377 N advance, 317 N return
- Ball cage guide for transverse forces up to 930 N and torques Mx 10 Nm, My 11 Nm, Mz 11 Nm
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.
