About the Airtac SAI50 Standard Cylinder SAI50AX50
The AirTAC SAI50X50 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 50 mm stroke makes it highly effective for short-travel clamping and indexing tasks where space is tight.
Built with a SUS420J2 stainless steel piston rod (option A), this unit provides excellent corrosion resistance for humid or mildly chemically exposed environments. It features PT tapered port threads and utilizes an extruded aluminum barrel with integrated sensor grooves on both sides for straightforward switch mounting.

Where the Airtac SAI50 Standard Cylinder SAI50AX50 Is Used
Short-Stroke Clamping
Ideal for holding parts securely during machining or welding operations using its 982 N push force.
Package Diverting
Provides rapid actuation for sorting mechanisms and pushers on high-speed packaging conveyors.
Material Ejection
Delivers reliable, fast ejection of finished parts from molds and press lines.
Is the Airtac SAI50 Standard Cylinder SAI50AX50 the Right Cylinder?
This 50 mm bore provides a balanced middle ground between the 40 mm bore (628 N at 0.5 MPa) and the 63 mm bore (1559 N at 0.5 MPa). Choose this model when your application demands moderate force in a compact footprint.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to maintain position. If your machinery requires the load to stay fixed during an emergency stop or air loss, integrate an external pilot-operated check valve or select the SAIL variant with an air-released lock. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders.
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 SAI50AX50 FAQ
