Ultra-compact linear actuator featuring precision-ground guide rods and dual anti-rotation pins for exceptional lateral load resistance (up to 15N·m). The 40S variant includes built-in magnet slots for position sensing (compatible with CS1-series sensors). The innovative stepped piston design reduces air consumption by 18% compared to standard models while maintaining 200N thrust capacity. Lubrication-free operation with self-compensating wear adjustment through spring-loaded seal system.
- PCB handling robots - component insertion/removal
- Pharmaceutical blister packaging machines
- Semiconductor wafer clamping mechanisms
- Automotive dashboard assembly fixtures
- Textile machine thread tensioners
Installation protocol:
For vertical mounting, use counterbalance valves when loads exceed 5kg.
Adjust cushion screws clockwise to increase damping - perform tuning at 80%
of maximum operating pressure. Requires 5μm filtered air with ISO VG32
lubricator (optional for maintenance-free operation).
