About the Airtac SAI50 Standard Cylinder SAI50AX40
The AirTAC SAI50X40 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 40 mm stroke is ideal for short-travel clamping, ejecting, and positioning tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern pneumatic setups.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and scratch resistance compared to standard carbon steel. It utilizes PT tapered port threading for its G1/4 air connections, ensuring a reliable, mechanically sealed fit.

Where the Airtac SAI50 Standard Cylinder SAI50AX40 Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa, ideal for securing workpieces during machining or welding operations.
Package Ejection
The 40 mm stroke offers rapid retraction and extension to push items off a conveyor line without occupying excessive space.
Gate Diverting
Actuates small pneumatic gates and sorting arms where a compact 50 mm bore delivers sufficient thrust to redirect materials.
Is the Airtac SAI50 Standard Cylinder SAI50AX40 the Right Cylinder?
Select this 50 mm bore when an application requires around 982 N of push force at 0.5 MPa, bridging the gap between the 40 mm (628 N) and 63 mm (1559 N) models. Because the 40 mm stroke is very short, side-load stress on the rod bearing is minimal, making it highly durable for high-cycle operations.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 50x40 mm ISO 15552 unit. If your sequence requires intermediate stopping or load holding without live air pressure, remember that standard air cushions only decelerate the piston; you must integrate an external rod lock or specify the SAIL variant for true holding power.
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 SAI50AX40 FAQ
At an operating pressure of 0.5 MPa, the SAI50X40 generates a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X40 is dimensionally interchangeable per ISO 15552 standards. It shares the exact 50 mm bore, 40 mm stroke, and G1/4 port mounting interface of other standard ISO 15552 profile cylinders, allowing for a seamless direct replacement.
