Description
Product Category: Welding Clamping Cylinder
Brand: AirTAC
Series: F-JCK-LM Adjusting Screw
A precision-engineered pneumatic actuation component designed for welding fixture applications. The F-JCK-LM series features a robust threaded adjustment mechanism with fine-tuning capability for precise stroke control and position calibration in automated welding systems. Its hardened steel construction ensures wear resistance under high-cycle operations, while the anti-corrosion surface treatment guarantees performance stability in harsh industrial environments. Integrated with standardized mounting interfaces (ISO 6432 compliant) for seamless integration with welding jigs and robotic arms. Optional locking nut configuration prevents unintended positional drift during continuous vibration exposure. Typical applications include spot welding positioners, assembly line clamping fixtures, and CNC welding automation setups.
Maintenance protocol:
Apply lithium-based grease (NLGI #2) to threads every 2,000 cycles.
Use torque wrench for re-tightening - do not exceed 18N·m.
Avoid chemical contact with chlorinated solvents.
