About the Airtac SAI50 Standard Cylinder SAI50AX260
The AirTAC SAI50X260 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 260mm stroke. It delivers a robust push force of 982 N at 0.5 MPa, extending to 1767 N at 0.9 MPa, making it well-suited for medium-duty handling and clamping tasks.
This specific configuration uses an SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in humid production zones. It features PT tapered port threads and, lacking the -S suffix, is built without a magnet for standard actuation.

Where the Airtac SAI50 Standard Cylinder SAI50AX260 Is Used
Mid-Force Clamping
Secures machined metal parts during milling or drilling using its 982 N push force at 0.5 MPa.
Package Diverting
Extends 260mm to push medium-weight cardboard cartons off a main packaging conveyor line.
Pneumatic Pressing
Drives lightweight bearings into housings on an automated assembly line.
Is the Airtac SAI50 Standard Cylinder SAI50AX260 the Right Cylinder?
This 50mm bore provides a balanced step up from the 40mm bore (628 N at 0.5 MPa) without the bulk of the 63mm bore (1559 N at 0.5 MPa). Because the 260mm stroke exceeds the 300mm side-load threshold, use an external guide rail or a guided cylinder carriage to prevent rod-bearing bending under offset loads.
As an ISO 15552 profile cylinder, it offers a direct dimensional replacement for other standard cylinders. Mount it using FA/FB flanges or TC trunnion brackets, and note that this non-magnetic variant cannot support CMSE/DMSE position sensing. If your process requires fail-safe mid-stroke holding without live air pressure, select the SAIL lock variant instead.
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 SAI50AX260 FAQ
At 0.5 MPa operating pressure, it provides 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force is 200 kgf.
Yes. It is built to the ISO 15552 mounting interface, meaning its envelope and mounting dimensions are interchangeable with other ISO 15552 profile cylinders of the same bore size.
