About the Airtac SAI63 Standard Cylinder SAI63AX180
The AirTAC SAI63X180 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 180mm stroke. It delivers a robust push force of 1559 N at 0.5 MPa, making it highly effective for mid-range industrial actuation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G3/8) and lacks a standard magnet, meaning it is optimized purely for mechanical drive tasks without requiring reed switch feedback.

Where the Airtac SAI63 Standard Cylinder SAI63AX180 Is Used
Packaging Machine Ejector
Provides the 1559 N push force needed to eject completed packages from a sealing station reliably.
Material Divert Gate
Actuates routing gates on a conveyor line, utilizing the 180mm stroke to clear product flow paths.
Press Stamper
Drives light-duty stamping and marking presses where a compact 63mm profile cylinder is required.
Is the Airtac SAI63 Standard Cylinder SAI63AX180 the Right Cylinder?
Choose this 63mm bore if you need substantially more power than the 50mm variant (982 N at 0.5 MPa) but want to avoid the larger footprint and air consumption of an 80mm cylinder (2513 N at 0.5 MPa). The 180mm stroke offers a practical extension range for packaging and material handling. Since this stroke is under 300mm, standard rod bearing bending is minimal, but always ensure axial load alignment to prevent premature seal wear.
As a standard double-acting cylinder, this model relies on continuous air pressure to hold its position. If your application involves vertical loads or requires fail-safe holding when air is exhausted, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. For exact mounting interchangeability, match the 63mm bore, 180mm stroke, G3/8 PT ports, and your required mounting accessory (like FA flange or TC trunnion).
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 SAI63 Standard Cylinder SAI63AX180 FAQ
At an operating pressure of 0.5 MPa, the SAI63X180 generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X180 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 63mm bore, 180mm stroke, and G3/8 port size.
