Airtac JCK High Strength Welding Clamping Cylinder JCK40X90AM3RK
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).

Installation guidelines:
Use M8 mounting bolts (grade 8.8 or higher) with Loctite 243.
Maintain 0.5-1mm clearance between clamp arm and cylinder body during thermal expansion.
Lubricate with ISO VG32 hydraulic oil before initial operation.
Critical note:
Requires 5μm filtration for compressed air.
Avoid lateral forces exceeding 10% of max thrust.
Cycle rate limited to 80% duty cycle at maximum stroke speed (500mm/s).
