About the Airtac SAI50 Standard Cylinder SAI50AX105
The AirTAC SAI50X105 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 105mm stroke. It provides a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design eliminates tie rods while maintaining strict dimensional interchangeability for direct replacements.
This specific configuration incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance in harsher environments. It utilizes PT tapered port threads and lacks an internal magnet. For operations requiring end-of-stroke position detection, the -S variant with dual-side sensor grooves would be required.

Where the Airtac SAI50 Standard Cylinder SAI50AX105 Is Used
Medium-Duty Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing machined components during milling or drilling operations.
Package Diverting
The 105mm stroke offers precise actuation for diverting medium-weight packages on sorting lines without occupying excessive footprint.
Material Ejection
Delivers consistent ejection force for molded parts or stamped sheet metal, utilizing the durable SUS420J2 rod to withstand minor impacts.
Is the Airtac SAI50 Standard Cylinder SAI50AX105 the Right Cylinder?
Choose this 50mm bore when an application demands 982 N of push force at 0.5 MPa, bridging the gap between the 40mm bore (628 N) and the 63mm bore (1559 N). The 105mm stroke is optimal for compact transfers and clamping. If your workflow requires holding a load vertically without continuous air pressure, remember that the standard adjustable air cushions only decelerate the piston and do not act as a lock; consider the SAIL or BSAI variants for secure clamping.
As a true ISO 15552 cylinder, it matches the mounting interfaces of other standard profile cylinders via FA/FB flanges or LB foot brackets. Ensure your piping matches the PT G1/4 port thread. Because the stroke is under 300mm, standard rod bearing bending stress is minimal, but always verify side loads remain within guide tolerances.
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 SAI50AX105 FAQ
At an operating pressure of 0.5 MPa, the SAI50X105 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 SAI50X105 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other standard ISO 15552 cylinders. Just ensure your setup accommodates the PT G1/4 port thread.
