Airtac JCK High Strength Welding Clamping Cylinder JCK40X75
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).

Robust welding clamp cylinder engineered for high-torque holding applications, featuring triple-layer chromium-plated piston rod and anti-spatter silicone coating. The through-rod design enables balanced force distribution, while the heavy-duty base absorbs vibration in continuous welding operations. Requires 5μm filtered air with ISO 8573-1:2010 class 4.4.3 air quality.
- Robotic welding fixture positioning systems
- Automotive chassis component jigging
- High-temperature metal stamping press clamping
- Foundry mold locking mechanisms
- Battery pack assembly compression fixtures
Installation protocol:
Mount with M8 grade 8.8 fasteners using 20N·m torque. Apply high-temperature
molybdenum grease to rod before initial use. Maintain 50mm clearance from
welding arc zone. Perform weekly purge cycling during standby periods.
