A high-rigidity workhorse cylinder featuring wear-resistant chromium rod plating and precision honed tube. The SI40AX140 delivers smooth linear motion with 0.5mm/s minimum creep speed capability. Its non-rotating piston design ensures precise load guidance, while the dual cushion adjustment prevents end-impact damage. Compatible with magnetic sensors (separately ordered) for position feedback.
- Packaging machinery clamp positioning
- CNC machine tool chip conveyors
- Automotive welding fixture actuation
- Pharmaceutical blister packaging systems
- Food processing conveyor gate control
