This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X22, 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 SI32X22
The AirTAC SI32 Standard Air Cylinder SI32X22 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 22mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X22, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X22
The AirTAC SI32X22 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 22 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced it with the SAI32X22 direct replacement, retaining the exact ISO 15552 mounting interface, G1/8 port, and 82 kgf maximum force. Note that 22 mm is a nonstandard stroke.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sensing, this no-magnet SKU cannot take a switch. For load holding, the cushion only decelerates; use a SAIL lock or pilot check valve.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X22 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X22 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X22 Is Used
Small Part Clamping
Ideal for holding lightweight machined components during secondary milling or drilling operations using the 402 N push force.
Ejector Mechanisms
Provides compact 22 mm ejection strokes to push finished small parts out of automated jigs and test fixtures.
Gate Diverting
Actuates small pneumatic diverter gates in packaging lines where a short, fast 30-800 mm/s transition is required.
Replacing the Airtac SI32 Standard Air Cylinder SI32X22 with the SAI32X22
To replace the SI32X22, order the SAI32X22 and confirm the ISO 15552 interface, 32 mm bore, 22 mm nonstandard stroke, G1/8 port, and mounting. This SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. Sizing both ways: a 40 mm bore offers 628 N push @0.5 MPa, while dropping pressure to 0.4 MPa yields ~321 N. For load holding, a plain cylinder drifts on air loss—use the SAIL lock variant or an external pilot check valve. If you need integrated valves, the SAIF variant (bores 32-100) is an option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X22
- ✓ 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 SI32X22 FAQ
Yes, the SI32X22 is discontinued. The direct replacement is the SAI32X22. It is dimensionally interchangeable per ISO 15552, matching the 32 mm bore, 22 mm stroke, G1/8 port, and mounting fixtures.
The G1/8 port bore delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
