This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X700, 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 SI32X700
The AirTAC SI32 Standard Air Cylinder SI32X700 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 SAI32X700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X700
The AirTAC SI32X700 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 700 mm stroke. Delivering 402 N push at 0.5 MPa via a G1/8 port, it is replaced by the SAI32X700. This direct upgrade shares identical mounting, force, and interface dimensions.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. Note this non-magnet SKU cannot take a sensor; the SI used CS1-B/DS1-B switches. Viton H seals raise heat to 150 C.

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 SI32X700 Is Used
Extended Transfer Pushing
Moves light packages along a 700 mm conveyor section where a compact 32 mm bore and 402 N output at 0.5 MPa is sufficient.
Bin Diverting Mechanism
Acts as a long-reach diverter arm for small totes, utilizing the 700 mm stroke to clear the main conveyor path completely.
Test Fixture Actuation
Drives a 700 mm linear motion in lab equipment, taking advantage of the 32 mm profile barrel and adjustable 27 mm cushions.
Replacing the Airtac SI32 Standard Air Cylinder SI32X700 with the SAI32X700
To replace the SI32X700, order the SAI32X700. Confirm the ISO 15552 interface, 32 mm bore, 700 mm stroke, G1/8 port, and mounting accessory. This non-S SKU lacks a magnet and cannot accept a sensor. For sizing, a 40 mm bore yields 628 N push at 0.5 MPa, while dropping to 25 mm lowers force. At 700 mm, prevent rod bending by using an external guide to manage side loads. The plain cylinder drifts without air; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X700
- ✓ 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 SI32X700 FAQ
Yes, the SI32X700 is discontinued. The direct replacement is the SAI32X700. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 700 mm stroke, output force, and G1/8 port.
The 32 mm bore uses a G1/8 port. Forces 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 max of 82 kgf at 1.0 MPa. Speed is 30-800 mm/s.
