Airtac JCK High Strength Welding Clamping Cylinder JCK40X120AM1RKN
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 clamp cylinder engineered for high-load fixturing in welding applications. Features reinforced weld-resistant construction with heat-deflecting barrel coating. The dual-lip rod seal prevents spark ingress, while the 3-stage cushioning system enables precise end-position control even at maximum 800mm/s speeds. Requires ISO VG32 hydraulic oil mist lubrication in continuous duty cycles.
- Robotic welding jigs in automotive assembly
- High-temperature furnace door clamping
- Press brake tooling positioning systems
- Forging machine workpiece retention
- Heavy part fixturing in shipbuilding
Installation protocol:
Mount using Class 8.8 M8 bolts with spring washers. Maintain 0.5–1mm gap between clamp arm and cylinder rod end to prevent side load. Perform 500-hour maintenance cycles using AirTAC PG-01 grease.
