About the Airtac SAI100 Standard Air Cylinder SAI100AX500
The AirTAC SAI100X500 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa across its 500 mm stroke. Its extruded aluminum barrel omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 standard actuators.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and is prepared without a magnet, meaning it is optimized for mechanical positioning rather than electronic switch sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX500 Is Used
Automated Pressing
Provides 3927 N of thrust at 0.5 MPa for pressing bearings or pins into housings along a guided 500 mm travel path.
Heavy Material Handling
Ideal for actuating heavy lifting gates or diverter arms on large-scale conveyor systems requiring a 500 mm reach.
Large Door Actuation
Drives the opening and closing of substantial industrial machine safety doors or heavy access panels over a half-meter span.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX500 the Right Cylinder?
With a 500 mm stroke, this 100 mm bore cylinder generates substantial thrust; if your application requires less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa. Conversely, moving up to the 125 mm bore provides 6136 N. Because the stroke is 500 mm, the unsupported rod is highly susceptible to bending under side loads; always utilize external guide rails or a guided cylinder carriage to prevent rod-bearing damage.
For any mechanism that must hold a load mid-stroke or during a complete air loss, remember that standard double-acting cylinders drift under pressure loss. The adjustable air cushions at both ends only decelerate the piston near the stroke ends and do not act as a brake. Implement an external pilot-operated check valve or select the SAIL locking variant for true position holding.
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 SAI100 Standard Air Cylinder SAI100AX500 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X500 features a standard ISO 15552 mounting interface and a G1/2 port, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same bore size.
