About the Airtac SAI32 Standard Cylinder SAI32AX70
The AirTAC SAI32X70 is a double-acting ISO 15552 profile cylinder engineered for compact automation. It delivers a push force of 563 N at 0.7 MPa, making the 70 mm stroke well-suited for short, rapid clamping or ejecting tasks.
This unit incorporates a SUS420J2 stainless steel piston rod for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI32 Standard Cylinder SAI32AX70 Is Used
Part Ejection
Ideal for pushing finished components out of a machining fixture with 563 N of force over a 70 mm travel distance.
Sorting Diverter
Provides rapid actuation to divert small packages or parts on a conveyor line where space is restricted.
Clamping Jig
Secures lightweight workpieces in assembly jigs, utilizing its SUS420J2 stainless rod to resist environmental moisture.
Is the Airtac SAI32 Standard Cylinder SAI32AX70 the Right Cylinder?
Select this 32 mm bore when an application requires roughly 563 N of push force; if you need less thrust, stepping down is not an option in this series, but moving up to a 40 mm bore yields 879 N at 0.7 MPa. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal.
For direct compatibility, match the 32 mm bore, 70 mm stroke, PT G1/8 port, and your required mounting accessory like an LB foot or FA flange. Note that this standard cylinder will drift if air pressure is lost; use a SAIL variant if the load must be mechanically held.
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 SAI32AX70 FAQ
At an operating pressure of 0.7 MPa, the SAI32X70 generates a push force of 563 N and a pull force of 345 N at 0.5 MPa.
Yes, the SAI32X70 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 cylinders with a 32 mm bore and 70 mm stroke, provided your port and mounting match.
