About the Airtac SAI50 Standard Cylinder SAI50BX230S
The AirTAC SAI50X230-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. The 230 mm stroke provides the extended travel needed for indexing, clamping, and automated assembly tasks. As a standardized profile barrel design, it offers a direct replacement for other ISO 15552 cylinders without requiring custom mounting plates.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance in wet or mildly chemically exposed environments. It is built with PT tapered port threads, and the integrated magnet (-S) allows direct mounting of CMSE or DMSE sensor switches along the dual grooves machined into the extruded aluminum barrel.

Where the Airtac SAI50 Standard Cylinder SAI50BX230S Is Used
Stainless Component Handling
The SUS304 rod resists washdown chemicals, making it ideal for actuating lifting forks in food-grade or medical parts handling.
Package Diverting
Provides the 982 N push force required to deflect heavy cartons off a main conveyor belt into secondary packaging lanes.
Pneumatic Clamping
Delivers reliable 825 N pull force to secure workpieces against machining fixtures during automated tooling cycles.
Is the Airtac SAI50 Standard Cylinder SAI50BX230S the Right Cylinder?
Choose this 50 mm bore when an application requires stepping up from the 40 mm bore class, which provides 628 N at 0.5 MPa, but does not warrant the larger 63 mm class and its 1559 N output. Because the 230 mm stroke creates an unsupported length, long rods are susceptible to bending under side loads. Implement an external guide rail or use a guided cylinder to prevent premature rod-bearing wear.
To match this cylinder exactly for an ISO 15552 replacement, specify the 50 mm bore, 230 mm stroke, PT G1/4 port, and the required mounting accessory (such as an LB foot or FA flange). Note that standard SAI cylinders rely on air pressure to move; they do not hold position when air is exhausted. If the machine requires dead-stop holding, select the SAIL variant with an air-released lock or use an external pilot-operated check valve.
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 SAI50BX230S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X230-S is dimensionally interchangeable per ISO 15552. It shares the same mounting interface and G1/4 port size, allowing it to serve as a direct replacement for other ISO 15552 profile cylinders.
