The ACQ series represents AirTAC's space-optimized cylinder solution featuring a 62% reduced cross-section compared to standard ISO cylinders. The ACQ40X250S combines extended stroke capability with a compact 50x50mm profile, achieved through precision-machined guide rails and integrated cushioning. Requires 5μm filtered lubricated air (ISO 8573-1 class 4) for optimal performance.
- High-density automation workstations
- PCB handling robots in electronics manufacturing
- Medical device assembly lines
- Vertical lift mechanisms in packaging machinery
- Automotive welding fixture positioning
Installation guidelines:
For vertical mounting, use tandem cylinders or external guides when handling
side loads exceeding 15N. Lubricate through air supply (ISO VG32 recommended)
with 1-2 drops oil/m³ air ratio. Avoid direct side impact forces.
