About the Airtac SAI32 Standard Cylinder SAI32AX70S
The AirTAC SAI32X70-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit features a 70 mm stroke that excels in short-travel positioning tasks. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. Equipped with a magnetic piston (-S), it supports CMSE and DMSE sensor switches fitted into the dual side grooves. Fluid ports feature PT tapered threads, and the cylinder incorporates adjustable air cushions at both ends to absorb end-of-stroke impact.

Where the Airtac SAI32 Standard Cylinder SAI32AX70S Is Used
Small Part Ejection
Provides the precise 563 N punch needed to eject small plastic components from molding machines without damaging the product surface.
Package Diverting
Drives short-stroke diverting arms on packaging lines, using the 70 mm travel to push lightweight cartons onto secondary conveyors.
Clamp Actuation
Actuates small pneumatic clamps in woodworking jigs, where the SUS420J2 rod resists environmental moisture and sawdust.
Is the Airtac SAI32 Standard Cylinder SAI32AX70S the Right Cylinder?
Select this 32 mm bore when an application requires roughly 400 N of push force at 0.5 MPa, or step up to the 40 mm bore if your load demands 628 N. The 70 mm stroke is optimal for tight spaces where a standard 50 mm or 100 mm travel would be too restrictive. Because the SAI32X70-S uses adjustable air cushions rather than a mechanical lock, it cannot hold a load vertically if air pressure is lost; for suspended loads that require safety holding, consider the SAIL pneumatic lock variant.
As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other standard profile cylinders of the same bore. To retrofit, match the 32 mm bore, 70 mm stroke, PT G1/8 port, and your required mounting accessory—such as LB foot brackets or FA flanges. Ensure you specify the -S magnet if you need position detection.
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 SAI32AX70S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder 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 SAI32X70-S is built to the ISO 15552 standard, making its mounting dimensions and center distances interchangeable with other ISO 15552 profile cylinders of the same bore size, regardless of brand.
