High-rigidity dual rod cylinder featuring symmetrical force transmission and enhanced moment resistance. The twin rod design minimizes rotational deflection during operation, making it ideal for precision fixturing applications. Integrated adjustable cushioning allows fine-tuning of end-stroke deceleration (adjustment range: 3-15mm). Includes built-in magnet for position sensing compatibility.
- Precision clamping in CNC machining centers
- Vertical lifting mechanisms for assembly robots
- Material transfer gates in packaging lines
- Press tool alignment systems
- Glass handling equipment in solar panel production
- Automated inspection jig positioning
1. Maintain ≤0.1mm/m alignment tolerance during mounting
2. For vertical installations, use anti-rotation brackets (ARB-40 recommended)
3. Lubricate piston rods monthly with ISO VG32 hydraulic oil in high-cycle applications
4. Maximum side load capacity reduces by 40% when operating at >0.6 MPa
