About the Airtac SAI50 Standard Cylinder SAI50AX450
The AirTAC SAI50X450 is a double-acting ISO 15552 profile cylinder offering a 982 N push force at 0.5 MPa. Its 450 mm stroke provides the extended travel needed for packaging and material handling tasks. The extruded aluminum barrel design ensures rigid performance without external tie rods.
This specific configuration features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance. It uses PT tapered port threads and lacks a magnet, meaning it is optimized for pure pneumatic actuation without external sensor tracking.

Where the Airtac SAI50 Standard Cylinder SAI50AX450 Is Used
Long-Reach Diverting
Pushes products across wide conveyor belts over the 450 mm travel distance.
Pallet Push-Off
Exerts 982 N of force to push packaged goods off accumulation lanes.
Extended Ejection
Ejects molded parts clear of large press beds during automated unloading.
Is the Airtac SAI50 Standard Cylinder SAI50AX450 the Right Cylinder?
With a 982 N push force at 0.5 MPa, this 50 mm bore sits comfortably between the 40 mm (628 N) and 63 mm (1559 N) bores. Choose this model when you need moderate force over a long distance. Because the stroke is 450 mm, the extended rod is highly susceptible to bending under side loads. Always use an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This unit is dimensionally interchangeable per ISO 15552, allowing direct replacement for other ISO 15552 profile cylinders. It features PT ports and supports standard mountings like FA, FB, and TC. If your machinery requires position feedback, select the -S variant with a magnet to use CMSE or DMSE sensors.
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 SAI50AX450 FAQ
At 0.5 MPa, the SAI50X450 provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
No. At 450 mm, the extended rod is vulnerable to bending under side load. An external guide mechanism is required to prevent damage to the rod bearing and seals.
