This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X670S, 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 SI32X670S
The AirTAC SI32 Standard Air Cylinder SI32X670S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 670mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X670S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X670S
The AirTAC SI32X670S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 670mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X670S. This direct upgrade matches the original mounting, stroke, and force exactly.
The SAI uses an upgraded piston seal with two Y-shaped elements for low start-up pressure. The SAI family adds SAIL and BSAI lock variants the SI lacked.

Where the Airtac SI32 Standard Air Cylinder SI32X670S Is Used
Light-Part Ejection
Pushes small molded components out of a machining center onto a downstream conveyor using its 670mm reach.
Bin Diverting
Actuates a lightweight sorting flap across a 670mm gap to route small packages into different fulfillment lanes.
Film Web Tracking
Adjusts a low-friction guide roller on a packaging line, using the 32mm bore for delicate tension control.
Replacing the Airtac SI32 Standard Air Cylinder SI32X670S with the SAI32X670S
To replace the SI32X670S, order the SAI32X670S. Confirm the ISO 15552 interface, 670mm stroke, G1/8 port, and the -S magnet for CS1-B/DS1-B switches (the SAI uses current AirTAC switches). At 402N push @0.5MPa, you can step up to a 40mm bore for 628N if more force is needed. For the 670mm stroke, use external guides to prevent rod bending and side-load wear. The cushion only decelerates; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X670S
- ✓ 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 SI32X670S FAQ
Yes, the SI32X670S is discontinued. The direct replacement is the SAI32X670S, matching the 32mm bore, 670mm stroke, G1/8 port, and ISO 15552 mounting interface.
The 32mm bore uses a G1/8 port. It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
