About the Airtac SAI50 Standard Cylinder SAI50X250
The AirTAC SAI50X250 is a double-acting profile cylinder built to ISO 15552 dimensional standards, making it a direct replacement for other ISO 15552 cylinders. Delivering a push force of 982 N at 0.5 MPa, it fits medium-duty positioning tasks perfectly. The extruded aluminum barrel design omits tie rods for a clean exterior.
This 50mm bore unit comes standard with a carbon steel piston rod and tapered PT G1/4 ports. It lacks a magnet for sensors, but the extruded barrel features dual-side grooves ready for CMSE or DMSE switches if you later require position feedback.

Where the Airtac SAI50 Standard Cylinder SAI50X250 Is Used
Package Diverting
Provides 982 N of push force to reliably divert medium-weight packages on a sorting line.
Clamp Fixtures
Secures aluminum or composite workpieces during machining with a 250mm reach.
Pallet Stops
Acts as a physical stop gate for low-profile pallets entering a workstation.
Is the Airtac SAI50 Standard Cylinder SAI50X250 the Right Cylinder?
Choose this 50mm bore when you need more power than the 40mm version (628 N at 0.5 MPa) but want a smaller footprint than the 63mm class (1559 N). With a 250mm stroke, the extended rod is highly susceptible to bending under side load. Mount external guides or use a guided cylinder to prevent rod-bearing damage.
Air pressure loss causes the piston to drift, as the adjustable air cushions only decelerate the stroke end, not hold loads. For dead-stop holding, use an external pilot-operated check valve. Ensure your mounting setup matches the ISO 15552 interface, utilizing accessories like FA flanges or TC trunnions, and add the -S magnet option if proximity sensing is needed.
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.
