Ultra-compact dual-action cylinder featuring corrosion-resistant stainless steel construction and bidirectional position adjustment. The twin-rod design enables balanced force distribution (5.6N at 0.5MPa) and precise mid-stroke positioning. Integrated adjustable cushions prevent end-impact damage, while the 40S variant includes reinforced rod bearings for high lateral load resistance.
- Precision alignment in semiconductor wafer handling
- Dual-gripper coordination in pick-and-place robots
- Medical device actuation requiring hygienic surfaces
- Food packaging machinery with frequent washdowns

Installation tip:
For optimal performance, maintain 0.5-1mm axial clearance during mounting.
Use locknuts (included) for stroke adjustment – clockwise rotation reduces stroke by 1.25mm per full turn.
Maintenance note:
Avoid silicone-based lubricants. Perform monthly rod surface inspection
when used in environments with particulate contamination.
