This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX100S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI32 Standard Air Cylinder SI32AX100S
The AirTAC SI32 Standard Air Cylinder SI32AX100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX100S
The AirTAC SI32AX100S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 100mm stroke. Featuring a SUS420J2 stainless steel rod and an integrated magnet for CS1-B/DS1-B switches, it delivers 402N push force at 0.5MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32AX100S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and cushioning.
The SAI replacement introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Beyond the standard line, the SAI family adds variants the SI lacked, including SAIL air-released locks, SAIF integrated 4M valves, and BSAI clamp-locks.

Where the Airtac SI32 Standard Air Cylinder SI32AX100S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of fixtures, utilizing the 402N push force and 100mm stroke for reliable separation.
Package Diverting
Sort small cartons on packaging lines where a compact 32mm bore and G1/8 port provide fast 30-800mm/s actuation without taking up space.
Gripping Jaws
Drives small pneumatic grippers in electronics assembly, where the SUS420J2 stainless rod offers corrosion resistance for clean environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX100S with the SAI32AX100S
To replace the SI32AX100S, order the SAI32AX100S. Confirm the ISO 15552 mounting interface (LB, FA, FB, CA, CB, TC), the 100mm stroke, the G1/8 port thread (PT/G/NPT), and the -S magnet for legacy CS1-B/DS1-B sensors. The SAI uses current AirTAC switches. For sizing, neighbouring bores like 40mm offer 628N push at 0.5MPa if more force is needed, while dropping to 0.5MPa on this 32mm bore still yields 402N push and 345N pull. Note that a plain SAI does not hold load on air loss; the cushion only decelerates. For load holding, specify the SAIL lock variant or an external pilot check valve. The -A rod denotes SUS420J2 stainless steel for corrosion resistance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32AX100S FAQ
Yes, the AirTAC SI32AX100S is discontinued. The direct replacement is the SAI32AX100S. It shares the same ISO 15552 mounting interface, 32mm bore, 100mm stroke, G1/8 port, and output force, fitting directly into existing fixtures.
This 32mm bore cylinder features a G1/8 air port and provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum force of 82kgf at 1.0MPa.
