Airtac JCK High Strength Welding Clamping Cylinder JCK40X90AM3R
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-stress welding applications. Features triple-sealed construction with anti-spatter coating (2-5μm thickness) on exposed surfaces. The reinforced AM3R mounting configuration enables 360° adjustable positioning and withstands lateral forces up to 300N. Requires 5μm filtered air with automatic lubricator (ISO VG32 recommended).
- Robotic welding fixture systems in automotive production
- Heavy plate positioning in shipbuilding jigs
- High-temperature mold clamping for die casting
- Precision alignment in battery pack assembly lines
- Forging machine tool holding mechanisms
Installation note:
Maintain coaxial alignment within 0.2mm during mounting. Apply thread locker (Loctite 243 recommended)
on mounting bolts tightened to 25-30N·m torque. Always engage mechanical lock before welding operations.
Critical:
Must install heat-resistant shield (sold separately) when ambient temperature exceeds 150℃.
Replace seals every 500,000 cycles or 12 months in continuous operation.
