Description
JCK Heavy-duty Welding Clamp Cylinder
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).
Category: Welding Clamping Cylinders | Brand: AIRTAC | Series: JCK
Installation protocol:
Use M6×25 mounting screws (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 and 20μm particulate separator in compressed air lines.
Absolute pressure must not exceed 0.85MPa to prevent weld seam failure.
Perform torque checks every 500,000 cycles in continuous operation.
