This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X800FTC, 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 SI32X800FTC
The AirTAC SI32 Standard Air Cylinder SI32X800FTC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 800mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X800FTC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X800FTC
The AirTAC SI32X800FTC is a discontinued double-acting ISO 15552 profile cylinder with an 800 mm stroke and FTC trunnion mount. Delivering 402 N push force at 0.5 MPa, it features a G1/8 port and M10x1.25 rod thread. The direct replacement is the SAI32X800FTC, matching the bore, stroke, force, port and mounting interface exactly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this specific SKU lacks the -S magnet, it cannot accept a CS1-B or DS1-B sensor. The SAI family also adds SAIL, SAIF and BSAI lock variants absent from the SI line.

Where the Airtac SI32 Standard Air Cylinder SI32X800FTC Is Used
Light Item Diverting
Pushes small packages along a packaging line using the 402 N force and 800 mm extension to clear the conveyor belt entirely.
Long Reach Sorting
Categorizes totes in distribution hubs where the 800 mm stroke moves products across wide sorting chutes with FTC trunnion stability.
Pneumatic Transfer Gates
Actuates diverter gates in material handling systems, utilizing the 30-800 mm/s speed range for rapid, repeatable transitions.
Replacing the Airtac SI32 Standard Air Cylinder SI32X800FTC with the SAI32X800FTC
To replace the SI32X800FTC, order the SAI32X800FTC. It drops into existing fixtures via the identical ISO 15552 mounting interface, preserving the 32 mm bore, 800 mm stroke, G1/8 port and FTC trunnion accessory. When sizing, note the 402 N push at 0.5 MPa; if more force is needed, step up to the 40 mm bore (628 N push). This SKU has no -S magnet, so it cannot support position sensing. As a plain double-acting cylinder, it will not hold a load without live air—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL lock variant. Finally, the 800 mm stroke demands external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X800FTC
- ✓ 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 SI32X800FTC FAQ
Yes, the SI32X800FTC is discontinued. The direct replacement is the SAI32X800FTC. It is dimensionally interchangeable per ISO 15552, keeping the same 32 mm bore, 800 mm stroke, G1/8 port and FTC mount.
It has a G1/8 port. The 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 max of 82 kgf at 1.0 MPa.
