About the Airtac SAI160 Standard Cylinder SAI160BX290S
The AirTAC SAI160X290-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 14074 N at 0.7 MPa, this 160mm bore unit is built to drive substantial loads over its 290mm stroke. The extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It is equipped with a magnet (-S) for seamless integration with CMSE or DMSE sensor switches fitted into the dual side grooves. Fluid ports feature PT tapered threading, and the cylinder incorporates adjustable air cushions at both ends to decelerate massive loads smoothly.

Where the Airtac SAI160 Standard Cylinder SAI160BX290S Is Used
Heavy Metal Forming
Drives large stamping and press operations requiring massive thrust, utilizing its 14074 N push force at 0.7 MPa to form thick gauge materials reliably.
Automotive Assembly Jigs
Actuates heavy clamping fixtures on automotive production lines, where the SUS304 rod provides necessary resilience against coolant and washdown chemicals.
Pallet Handling Systems
Pushes loaded pallets or heavy totes through high-cycle sorting stations, relying on adjustable air cushions to absorb kinetic energy at stroke end.
Is the Airtac SAI160 Standard Cylinder SAI160BX290S the Right Cylinder?
Selecting this 160mm bore is ideal when a 125mm cylinder falls short, as the 125mm bore yields only 8590 N at 0.7 MPa. If your application requires less force, stepping down to a 125mm bore saves space and air consumption. Because this 290mm stroke approaches the threshold for side-load vulnerability, ensure the load is guided externally to prevent rod-bearing bending and premature seal wear.
This model is a dimensionally interchangeable direct replacement for other ISO 15552 cylinders. To match this exact configuration, specify the 160mm bore, 290mm stroke, PT port thread, your desired mounting accessory (such as LB foot or TC trunnion), and the -S magnet option. Note that a standard SAI does not hold position if air pressure is lost; for dead-load holding, consider the SAIL or BSAI clamp-lock variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
