This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X215S, 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 SI32X215S
The AirTAC SI32 Standard Air Cylinder SI32X215S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 215mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X215S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X215S
The AirTAC SI32X215S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 215mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X215S, matching the exact bore, stroke, force, port and mounting interface for existing fixtures.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -S suffix means a piston magnet for legacy CS1-B/DS1-B sensors; the SAI uses current AirTAC switches. Note 215mm is a non-standard stroke.

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 SAI32X215S 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 SI32X215S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture without damaging the surface.
Package Diverting
Actuates a diverter arm on a packaging line, where the 345N pull force and 215mm stroke reliably route small boxes.
Compact Clamping
Secures light workpieces in an assembly jig, taking advantage of the 32mm profile barrel to fit tight cell spaces.
Replacing the Airtac SI32 Standard Air Cylinder SI32X215S with the SAI32X215S
To replace the SI32X215S, order the SAI32X215S. Verify the ISO 15552 mounting interface, 32mm bore, 215mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. The -S magnet is required for switch sensing. If you need more force, the 40mm bore yields 628N push at 0.5MPa; if less is acceptable, there is no smaller ISO 15552 bore. Because 215mm is a non-standard stroke, confirm availability. For strokes over 300mm, guide rods prevent side-load bending, though 215mm is moderate. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X215S
- ✓ 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 SI32X215S FAQ
Yes, the AirTAC SI32X215S is discontinued. The direct replacement is the SAI32X215S. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 215mm stroke, 402N force, G1/8 port and mounting interface.
The 32mm bore uses a G1/8 port. Theoretical forces are: 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum force of 82kgf at 1.0MPa.
