Description

The mini slide DGST-20-40-PA makes a separate guide on the cylinder unnecessary. The ball cage guide is built in, the stroke is 40 mm with a 20 mm piston. Inside the housing, two pistons of 20 mm diameter each act in parallel on the yoke.

Benefits

  • End position cushioning: flexible cushioning rings at both ends, permissible impact energy 0.35 J
  • Theoretical force at 6 bar: 377 N advance, 317 N return
  • Travel speed up to 0.8 m/s
  • Repetition accuracy ≤ 0.3 mm for reproducible end positions
  • End position range adjustable over 32 mm at the front and 31.5 mm at the rear
  • Ball cage guide for transverse forces up to 930 N and torques Mx 10 Nm, My 11 Nm, Mz 11 Nm

Applications

Typical tasks are feeding, aligning and pick-and-place in assembly and test systems. Any mounting position is possible, mounting is with through-hole, compressed air is supplied via G1/8. End positions can be sensed with proximity switches.
