About the Airtac SAI160 Standard Cylinder SAI160AX250S
The AirTAC SAI160X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 14074 N of push force at 0.7 MPa, this 160 mm bore unit is built to move substantial masses across its 250 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a magnet for non-contact position sensing, working seamlessly with CMSE and DMSE switches housed in the dual sensor grooves. Furthermore, the piston rod utilizes SUS420J2 stainless steel (material code A), offering excellent corrosion resistance and mechanical strength for harsh industrial environments.

Where the Airtac SAI160 Standard Cylinder SAI160AX250S Is Used
Heavy-Duty Stamping
Generates 14074 N of thrust at 0.7 MPa to actuate large metal forming and stamping presses with stable, high-force clamping.
Automotive Assembly
Ideal for positioning heavy chassis components or applying structural adhesives on automated automotive manufacturing lines.
Pallet Handling
Drives robust diverters and lifting stations on heavy-gauge pallet conveyors, utilizing the 250 mm stroke to clear large pallet profiles.
Is the Airtac SAI160 Standard Cylinder SAI160AX250S the Right Cylinder?
Selecting this 160 mm bore makes sense when the 125 mm class (8590 N push at 0.7 MPa) is insufficient for your load requirements, but you want to avoid stepping up to the massive 200 mm bore (21991 N push at 0.7 MPa). The 250 mm stroke is well within the 1500 mm maximum standard stroke limit, making it a stock-friendly choice. It features PT tapered port threads and uses adjustable air cushions at both ends to manage end-of-stroke kinetic energy.
Because the stroke is 250 mm, side loads can place bending moments on the rod bearing. If your application involves heavy off-center loads, utilize an external guide rail or a dedicated guided cylinder to prevent premature seal wear and rod deflection. Note that the standard SAI does not hold position when air pressure is removed; for fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
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.
Airtac SAI160 Standard Cylinder SAI160AX250S FAQ
At a standard operating pressure of 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At 0.5 MPa, the push force is 10053 N.
