About the Airtac SAI32 Standard Cylinder SAI32AX550
The AirTAC SAI32X550 is a double-acting ISO 15552 profile cylinder engineered for extended reach applications. Delivering a push force of 563 N at 0.7 MPa, this non-standard 550 mm stroke unit is built to order for specialized linear motion tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
Configured here with SUS420J2 stainless steel rod material (code A) for enhanced corrosion resistance, this model features PT tapered port threads. Because it lacks a piston magnet, external position sensing must be achieved mechanically rather than using internal CMSE or DMSE switches.

Where the Airtac SAI32 Standard Cylinder SAI32AX550 Is Used
Extended Transfer Pushing
Pushes lightweight packages or product diverts along extended conveyor sections where a 550 mm reach is required to clear adjacent machinery.
Long-Reach Sorting
Actuates sorting arms in distribution centers, utilizing the compact 32 mm bore to fit within tight lane spacing while providing adequate 563 N force.
Material Dispense
Drives extended dispense heads or applicators across a wide work envelope, benefiting from the SUS420J2 stainless rod in mildly humid environments.
Is the Airtac SAI32 Standard Cylinder SAI32AX550 the Right Cylinder?
Selecting this 32 mm bore over the smaller 40 mm bore (which offers 879 N push at 0.7 MPa) is ideal when footprint constraints matter more than raw thrust. However, the 550 mm stroke exceeds the standard 500 mm limit for this bore, classifying it as a made-to-order item. For strokes of 300 mm or more, the unsupported rod is highly susceptible to bending under side loads; integrating an external guide rail or opting for a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model serves as a dimensionally interchangeable direct replacement per ISO 15552 mounting dimensions. When swapping, verify the 550 mm stroke, PT G1/8 port, and mounting accessory type. Note that a standard SAI does not hold its position if air pressure is lost; if mid-stroke locking is required for safety, specify the SAIL variant or use an external pilot-operated check valve.
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 SAI32AX550 FAQ
At an operating pressure of 0.7 MPa, the SAI32X550 generates a push force of 563 N and a pull force of 345 N. At 0.5 MPa, the push force is 402 N.
Yes, the SAI32X550 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders, provided you match the 32 mm bore, 550 mm stroke, and G1/8 port.
