This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X700S, 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 SI32X700S
The AirTAC SI32 Standard Air Cylinder SI32X700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 700mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X700S
The AirTAC SI32X700S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 700 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32X700S, a direct sharing the exact interface, bore, stroke, force, port and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF and BSAI lock variants the SI lacked.

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 SI32X700S Is Used
Light-Part Diversion
Pushes small packages on a 700 mm line using 402 N force, with the magnet confirming full extension.
Tooling Ejector
Cycles lightweight jigs out of a machine envelope, relying on the 32 mm bore compact profile.
Replacing the Airtac SI32 Standard Air Cylinder SI32X700S with the SAI32X700S
To replace the SI32X700S, order the SAI32X700S. Confirm the ISO 15552 mounting interface, 32 mm bore, 700 mm stroke, G1/8 port (PT/G/NPT) and the -S magnet for CS1-B/DS1-B switches. If you need more force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if less force is acceptable, drop to a smaller bore. Note that a 700 mm stroke demands external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X700S
- ✓ 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 SI32X700S FAQ
Yes, the SI32X700S is discontinued. The direct replacement is the SAI32X700S. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 700 mm stroke, output force, G1/8 port and mounting fixtures.
It is double-acting with a 12 mm rod, M10x1.25 thread, 27 mm cushion and 30-800 mm/s speed. Force ratings are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
