This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X600S, 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 SI32X600S
The AirTAC SI32 Standard Air Cylinder SI32X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 600mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X600S
The AirTAC SI32X600S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 600 mm stroke. Delivering 402 N push force at 0.5 MPa through a G1/8 port, it is replaced by the SAI32X600S. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI -S suffix means a piston magnet for CS1-B/DS1-B sensors; the SAI uses current AirTAC switches.

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

Where the Airtac SI32 Standard Air Cylinder SI32X600S Is Used
Light-Part Diversion
Pushes small packages on a packaging line using the 402 N push force, with the 600 mm stroke reaching across the conveyor width.
Long-Reach Ejection
Ejects light machined parts from a fixture, where the 32 mm bore fits tight spaces and the long stroke clears the machine envelope.
Replacing the Airtac SI32 Standard Air Cylinder SI32X600S with the SAI32X600S
To replace the SI32X600S, order the SAI32X600S. Confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/8 port thread (PT/G/NPT) and the magnet (-S). For sizing, neighbouring bores like 40 mm offer higher force (628 N push at 0.5 MPa), while 32 mm is optimal for lighter loads. Because the 600 mm stroke invites rod bending, use an external guide to prevent side-load damage. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X600S
- ✓ 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 SI32X600S FAQ
Yes, the SI32X600S is discontinued. The direct replacement is the SAI32X600S. It shares the identical ISO 15552 mounting interface, 32 mm bore, 600 mm stroke, output force and G1/8 port, fitting existing fixtures perfectly.
The 32 mm bore uses a G1/8 port. Force ratings are 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 of 82 kgf at 1.0 MPa.
