About the Airtac SAI160 Standard Cylinder SAI160AX20S
The AirTAC SAI160X20-S is a double-acting ISO 15552 profile cylinder engineered for high-force applications, delivering a substantial 14074 N of push force at 0.7 MPa. This 160 mm bore combined with a compact 20 mm stroke is purpose-built for heavy-duty clamping, riveting, and pressing operations requiring immense power over a short distance.
To suit demanding environments, this specific unit features a SUS420J2 stainless steel piston rod (option A) for superior corrosion and wear resistance compared to standard carbon steel. It includes a magnetic piston (-S) for seamless integration with CMSE or DMSE position sensing switches along the dual-side extruded aluminum barrel grooves, while utilizing PT tapered port threads.

Where the Airtac SAI160 Standard Cylinder SAI160AX20S Is Used
Heavy Stamping
Provides the 18095 N peak thrust at 0.9 MPa needed to form thick-gauge metal plates and heavy components in automated press lines.
Industrial Clamping
Secures massive workpieces during machining or welding operations, utilizing the short 20 mm stroke for rapid, high-force holding.
Riveting Assembly
Delivers consistent, high-impact kinetic energy to set large structural rivets in heavy equipment manufacturing.
Is the Airtac SAI160 Standard Cylinder SAI160AX20S the Right Cylinder?
Selecting this 160 mm bore is ideal when the 100 mm bore (providing 5497 N push at 0.7 MPa) is insufficient for your heavy press requirements, but you want to avoid the massive 200 mm footprint. Because the stroke is only 20 mm, rod-bearing bending and side-load stresses are negligible, meaning external guides are typically unnecessary for the actuator itself.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard ISO 15552 unit with a 160 mm bore, 20 mm stroke, G3/4 port, and matching mounting accessories like FA/FB flanges or TC trunnions. Note that the standard adjustable air cushions only decelerate the piston near the stroke ends; if your setup must hold a load mechanically without sustained air pressure, utilize the SAIL (pneumatic lock) 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.
Airtac SAI160 Standard Cylinder SAI160AX20S FAQ
At a standard operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. The maximum theoretical force at 1.0 MPa is 2050 kgf.
No, the standard SAI cylinder drifts when pressure is removed. The adjustable air cushions only slow the piston at stroke end, they do not act as a lock. For fail-safe load holding, use the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
