About the Airtac SAI50 Standard Cylinder SAI50X105S
The AirTAC SAI50X105-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 105mm stroke. It supplies a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The barrel is machined from extruded aluminum and includes integrated sensor grooves on both sides.
This specific configuration includes a magnet for position detection, allowing seamless integration with CMSE or DMSE reed switches. The piston rod is constructed from standard carbon steel, and the fluid port utilizes a PT tapered thread design to ensure a robust, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X105S Is Used
Package Diversion
Provides the 982N push force needed to actuate sorting gates and divert packages smoothly on high-speed material handling lines.
Clamping Fixtures
The 105mm stroke delivers precise clamping travel for holding workpieces securely during machining or assembly operations.
Gate Control
Ideal for automating process gates and access doors where a compact 50mm profile cylinder with reliable position feedback is required.
Is the Airtac SAI50 Standard Cylinder SAI50X105S the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm version upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to the 63mm bore yields 1559 N for heavier payloads. The 105mm stroke is a non-catalog standard increment but remains well within the 1200mm maximum limit, offering a precise fit for mechanisms requiring exact intermediate travel.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold its position; exhausting the air or centering the control valve will cause the piston to drift. If your application requires dead-stop load holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard mounting interface, utilizing a G1/4 port, FA/FB flanges, and the -S magnet option.
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 SAI50X105S FAQ
