This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X1200, 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 SI32X1200
The AirTAC SI32 Standard Air Cylinder SI32X1200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 1200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X1200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X1200
The AirTAC SI32X1200 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 1200mm stroke. Because 1200mm exceeds the 1000mm standard maximum for this bore, it is a non-standard, made-to-order size. Generating a push force of 402 N at 0.5 MPa, its direct replacement is the SAI32X1200, sharing the exact same ISO 15552 mounting interface, G1/8 port, and output force.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks the -S magnet, so it cannot accept CS1-B or DS1-B sensors.

Where the Airtac SI32 Standard Air Cylinder SI32X1200 Is Used
Extended Reach Diverters
Handles long-travel package routing on wide conveyor lines where a 1200mm extension is required to clear adjacent machinery.
High-Bay Pusher Arms
Pushes tote bins from storage racks into retrieval aisles, utilizing the 402 N push force to overcome initial sliding friction.
Vertical Lowering Dampers
Regulates the descent of light fixtures in automated assembly, relying on adjustable air cushions to decelerate the load near stroke end.
Replacing the Airtac SI32 Standard Air Cylinder SI32X1200 with the SAI32X1200
To replace the SI32X1200, order the SAI32X1200, verifying your ISO 15552 mounting accessory (LB, FA, TC, etc.) and G1/8 port thread (PT, G, or NPT). If your application requires position sensing, you must select an SAI variant with the magnet option, as this legacy SKU lacks one. For sizing alternatives, a 40mm bore offers 628 N push at 0.5 MPa, while dropping to a standard 1000mm stroke avoids custom manufacturing. Because this 1200mm stroke exceeds the bore's standard maximum, use external guides to prevent rod bending and side-load damage. A plain cylinder does not hold load on air loss; for load holding, consider the SAIL lock, BSAI clamp-lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X1200
- ✓ 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 SI32X1200 FAQ
Yes, the AirTAC SI32X1200 is discontinued. The direct replacement is the SAI32X1200. It is dimensionally interchangeable per ISO 15552, maintaining the same 32mm bore, 1200mm stroke, G1/8 port, and mounting interface, so it drops directly into existing fixtures.
This 32mm bore double-acting cylinder features a G1/8 air port and provides a push force of 402 N and pull force of 345 N at 0.5 MPa. At 0.7 MPa push is 563 N, at 0.9 MPa it is 724 N, and the theoretical maximum force is 82 kgf at 1.0 MPa.
