About the Airtac SAI160 Standard Cylinder SAI160BX140S
The AirTAC SAI160X140-S is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It delivers a substantial push force of 14074 N at 0.7 MPa, making it well-suited for moving large masses over its 140 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical interference.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh or washdown environments. Equipped with a built-in magnet (-S), it supports CMSE and DMSE sensor switches housed neatly within the dual-side grooves. It also features adjustable air cushions at both ends, providing 50 mm of cushioning travel to absorb high kinetic energy at stroke completion.

Where the Airtac SAI160 Standard Cylinder SAI160BX140S Is Used
Heavy Stamping
Provides the high thrust necessary for metal forming, pressing, and riveting operations requiring significant impact force.
Large Clamp Fixtures
Secures oversized automotive or aerospace components during machining with a robust 140 mm stroke.
Pallet Diversion
Actuates heavy-duty diverter arms on high-throughput packaging lines to reroute large palletized goods.
Is the Airtac SAI160 Standard Cylinder SAI160BX140S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (providing 5497 N push at 0.7 MPa) is insufficient to overcome your process load and friction. Because this model features a 140 mm stroke, it remains compact enough that excessive rod sagging is typically not a primary concern, though external guides are recommended if absorbing heavy side-impact loads. This cylinder uses G3/4 PT ports and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions.
If your machinery requires the load to be physically held in place during a complete loss of air pressure or an emergency stop, the standard adjustable air cushion will not prevent the piston from drifting. For fail-safe position holding, you must integrate an external pilot-operated check valve or select the AirTAC SAIL variant, which features a built-in pneumatic lock.
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 SAI160BX140S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes, the SAI160X140-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided your mounting interface and G3/4 port connections align.
