This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X588S, 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 SI32X588S
The AirTAC SI32 Standard Air Cylinder SI32X588S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 588mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X588S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X588S
The AirTAC SI32X588S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 588 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X588S, a direct upgrade retaining the exact interface, bore, stroke, and mounting hardware.
The SAI upgrade features a refined piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life. The original SI-S magnet supports legacy CS1-B/DS1-B sensors, while the SAI accepts current AirTAC switches. For high-temperature environments up to 150 C, a Viton H seal option is available.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SI32 Standard Air Cylinder SI32X588S Is Used
Long-Reach Ejection
Ejects machined components from deep fixtures, relying on the adjustable 27 mm air cushions to decelerate the rod gently at stroke ends.
Replacing the Airtac SI32 Standard Air Cylinder SI32X588S with the SAI32X588S
To replace the SI32X588S, order the SAI32X588S. Confirm the ISO 15552 mounting interface, 32 mm bore, 588 mm stroke, G1/8 port (PT/G/NPT thread options), and the -S magnet for position sensing. If you need more force, the neighbouring 40 mm bore offers 628 N push at 0.5 MPa; if less force is acceptable, verify your minimum operating pressure. Note that a plain cylinder does not hold load on air loss—the cushion only decelerates. For secure holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Because the 588 mm stroke is long, use external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X588S
- ✓ 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 SI32X588S FAQ
Yes, the SI32X588S is discontinued. The direct replacement is the AirTAC SAI32X588S. It is dimensionally interchangeable per ISO 15552, matching the 32 mm bore, 588 mm stroke, G1/8 port, and mounting interface.
This 32 mm bore cylinder has a G1/8 port. It 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 theoretical maximum force of 82 kgf at 1.0 MPa.
