About the Airtac SAI50 Standard Cylinder SAI50AX230S
The AirTAC SAI50X230-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 230mm stroke. It delivers a robust 982N of push force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring substantial travel. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in demanding environments. Equipped with a magnetic piston (-S), the barrel features integrated sensor grooves on both sides for direct mounting of CMSE or DMSE reed switches. You can also customize the standard TPU seals to high-temperature Viton (H) if your application exceeds normal thermal limits.

Where the Airtac SAI50 Standard Cylinder SAI50AX230S Is Used
Package Sorting Diverter
Provides the 982N push force needed to deflect heavy cartons across a high-speed conveyor belt system.
Component Press Fit
Uses the 230mm stroke to lower and press bearings into housings, leveraging the stable ISO 15552 mounting interface.
Pallet Stopper Gate
Actuates as a pneumatic stop gate for pallets on roller conveyors, benefiting from the durable SUS420J2 rod.
Is the Airtac SAI50 Standard Cylinder SAI50AX230S the Right Cylinder?
Selecting this 50mm bore is ideal when you need more thrust than the 40mm variant (628N at 0.5 MPa) but want to avoid the larger footprint and air consumption of the 63mm cylinder (1559N at 0.5 MPa). The 230mm stroke provides ample extension for packaging and material handling, while the PT tapered port thread ensures a tight, reliable pneumatic connection.
Because this model features a 230mm stroke, it approaches the threshold where side loads can stress the rod bearing. For applications involving heavy off-center loads, utilize external guide rails or a guided cylinder to prevent premature wear. Remember that a standard SAI cylinder does not hold position when air pressure is lost; if your workflow requires fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-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 SAI50 Standard Cylinder SAI50AX230S FAQ
At 0.5 MPa operating pressure, the SAI50X230-S provides a push force of 982N and a pull force of 825N. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X230-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders of the same bore and stroke, utilizing standard FA/FB flange or TC trunnion mounts.
