About the Airtac SAI63 Standard Cylinder SAI63AX75
The AirTAC SAI63X75 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 75 mm stroke provides a compact stroke length ideal for mid-range automation tasks. The extruded aluminum barrel design ensures structural rigidity without the need for external tie rods.
This specific unit is configured with an SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. It features PT tapered port threads and does not include a magnet, meaning it is not designed for direct mount reed or solid-state sensor integration.

Where the Airtac SAI63 Standard Cylinder SAI63AX75 Is Used
Assembly Presses
Provides reliable 1559 N push force at 0.5 MPa for pressing small bushings and bearings into housings within automated machinery.
Package Diverting
Drives mid-sized diverter arms on packaging lines where a 75 mm stroke is sufficient to redirect cartons between conveyor belts.
Material Grippers
Actuates heavy-duty mechanical grippers used in automotive component handling, utilizing the SUS420J2 rod to resist moisture.
Is the Airtac SAI63 Standard Cylinder SAI63AX75 the Right Cylinder?
Select this 63 mm bore when an application requires upward of 1559 N at 0.5 MPa, bridging the gap between the 982 N of a 50 mm bore and the 2513 N of an 80 mm bore. The 75 mm stroke offers rapid cycling for close-proximity assembly tasks. Because the standard SAI lacks a locking mechanism, the piston will drift if air pressure is lost; use an SAIL variant if the load must be mechanically held in place during exhaust.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a drop-in replacement for other ISO 15552 profile cylinders. When replacing, verify the 63 mm bore, 75 mm stroke, G3/8 PT port, and your required mounting accessory (such as an FA flange or TC trunnion). Ensure you select the non-magnet version if sensors are not required.
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.
