About the Airtac SAI32 Standard Cylinder SAI32AX115S
The AirTAC SAI32X115-S is a double-acting ISO 15552 profile cylinder offering a 32 mm bore and a 115 mm stroke. It delivers a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, making it well-suited for compact actuation tasks. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that simplifies mounting in tight machinery spaces.
This specific configuration includes a -S magnet for use with CMSE and DMSE series reed switches, fitting directly into the sensor grooves machined on both sides of the barrel. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (material code A), providing enhanced resistance to corrosion and surface wear compared to standard carbon steel rods.

Where the Airtac SAI32 Standard Cylinder SAI32AX115S Is Used
Small Parts Clamping
Provides reliable 563 N clamping force at 0.7 MPa for securing small aluminum or plastic components during light machining and assembly processes.
Package Diversion
Actuates diverter arms on packaging lines, utilizing the 115 mm stroke to push cartons smoothly between adjacent conveyor belts.
Gate Control
Operates small access gates and safety hatches on automated storage racks, benefiting from the compact 32 mm profile barrel design.
Is the Airtac SAI32 Standard Cylinder SAI32AX115S the Right Cylinder?
If 402 N of push force at 0.5 MPa is insufficient for your payload, stepping up to the 40 mm bore variant increases that output to 628 N. Conversely, if your application requires less force, no smaller standard SAI bore exists below 32 mm. Because this is a 115 mm stroke, side-loading is less prominent than in longer strokes, but ensuring proper rod alignment remains critical to prevent premature seal wear.
This SAI32X115-S serves as a direct replacement for any ISO 15552 cylinder with a 32 mm bore, 115 mm stroke, PT G1/8 port, and standard mounting accessories like FA flanges or LB foot brackets. Note that a standard SAI cylinder relies on continuous air pressure to hold its position; if your cycle requires dead-stop holding without live pressure, consider the SAIL or BSAI locking variants.
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 SAI32AX115S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X115-S is dimensionally interchangeable per ISO 15552. You can directly swap it with other 32 mm bore, 115 mm stroke ISO 15552 profile cylinders using the same mounting interface.
