About the Airtac SAI32 Standard Cylinder SAI32X550
The AirTAC SAI32X550 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 550mm stroke. Because 550mm exceeds the standard maximum of 500mm for this bore, it is a made-to-order unit delivering 402N of push force at 0.5MPa. The extruded aluminum barrel omits tie rods for a clean exterior.
This configuration uses a standard carbon steel piston rod and PT tapered port threads. Without a magnet, it does not support direct sensor mounting; if position detection is required, specify the -S option to enable CMSE or DMSE switches in the dual sensor grooves.

Where the Airtac SAI32 Standard Cylinder SAI32X550 Is Used
Small Component Ejection
Suitable for pushing lightweight parts out of machining centers over a 550mm travel distance using its 402N push force at 0.5MPa.
Long Transfer Arm
Acts as an extended reach arm on packaging lines, moving products between conveyor belts where a 32mm bore provides sufficient thrust.
Carton Diverting
Used in logistics sortation systems to deflect small cartons at 30-800mm/s operating speeds without occupying excessive footprint.
Is the Airtac SAI32 Standard Cylinder SAI32X550 the Right Cylinder?
Since 550mm exceeds the 32mm bore's standard maximum stroke of 500mm, this is a non-standard made-to-order stroke. For applications needing less travel, the SAI32X500 provides standard availability. The extended 550mm rod is susceptible to bending under side loads, so an external guide or a guided cylinder is recommended to prevent rod-bearing damage.
This model features a G1/8 port and M10x1.25 rod thread. As a standard double-acting cylinder, it will not hold a load if air pressure is lost; for position holding, consider the SAIL variant with an air-released lock. It is dimensionally interchangeable per ISO 15552.
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 SAI32 Standard Cylinder SAI32X550 FAQ
The SAI32X550 generates 402N of push force and 345N of pull force at 0.5MPa. At 0.7MPa, the push force increases to 563N.
Yes, the SAI32X550 is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing it to serve as a direct replacement using standard mounting accessories like LB or FA.
