Airtac JCK High Strength Welding Clamping Cylinder JCK40X135KN
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 specifically engineered for high-temperature welding environments. Features enhanced heat-resistant seals (up to 150℃ with optional FKM) and anti-spatter coating. The reinforced flange design withstands 20% higher side loads compared to standard cylinders. Requires 5μm filtered air and monthly lubrication intervals under continuous operation.
- Robotic welding fixture systems
- Automotive chassis assembly jigs
- High-temperature metal stamping positioning
- Foundry mold clamping operations
- Heavy-duty CNC machining workholding
Installation protocol:
Always install heat shields within 30cm of welding arcs. Use locknuts with 1.5x rated torque for vibration resistance.
Allow 15mm clearance behind rod end for thermal expansion.
