A high-performance compact cylinder featuring precision honed tubing and dual anti-rotation design. The SI40X40S delivers 502N thrust at 0.6MPa (push side) with smooth operation through its multi-lip seal system. Optimized for energy efficiency with ≤0.15 MPa minimum operating pressure. Requires ISO VG32 hydraulic oil mist lubrication for maximum seal life.
- Automated assembly line clamping mechanisms
- Textile machinery thread tension control
- Pharmaceutical blister packaging systems
- Automotive welding fixture positioning
- Semiconductor wafer handling robots
Installation note:
Mount using ISO 6432-compliant brackets only. Allow 0.5mm thermal expansion gap per meter during high-cycle (>50cpm) operations. Lubricate through air line oilers (drip rate: 1 drop/5 cycles) for optimal performance.
