1. Patented crank-slider mechanism (constructed with high-strength, wear-resistant materials): a) Ensures structural stability and generates exceptional clamping force with minimal air pressure through high mechanical efficiency. b) Integrated self-locking mechanism maintains clamping force even during air supply interruption.
2. DIN-compliant four-side mounting configuration for flexible installation options.
3. Monolithic design integrating clamping mechanism with pneumatic cylinder for enhanced structural integrity.
4. Specially engineered sensor bracket with anti-spatter design and ±15° adjustable angles, featuring anti-interference shielding for stable signal transmission.
5. Space-efficient oval-shaped cylinder housing optimizes equipment layout in confined spaces.
6. Modular clamp arms (AM1/AM2/AM3/AM4) with R/C/L variants (radial/vertical/lateral orientations) adapt to diverse operational demands.
7. Tool-free opening angle adjustment via replacement of adjustment screws (15°-180° range).

Industrial-grade clamping cylinder engineered for high-moment resistance in welding environments. Features a reinforced rod guide system (triple lip seals) and anti-rotation piston rod. The special PTFE-impregnated rod coating resists welding spatter adhesion. Requires 5μm filtered air with <30% relative humidity.
- Robotic welding fixture systems
- Automotive chassis component clamping
- Heavy part positioning in foundries
- Press brake tooling securement
- Forging machine workholding
- Mount using M8x1.25 screws (25Nm torque limit)
- Maintain 0.5-1mm clearance between magnetic sensor and slot
- Apply high-temperature grease (≥200℃ rating) to rod weekly in continuous operation
- Use 2:1 lever ratio for optimal clamping force distribution
