This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X800SFA, 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 SI32X800SFA
The AirTAC SI32 Standard Air Cylinder SI32X800SFA 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 SAI32X800SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X800SFA
The AirTAC SI32X800SFA is a discontinued double-acting ISO 15552 profile cylinder with an 800 mm stroke and FA flange. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced it with the SAI32X800SFA, a direct upgrade retaining the exact bore, stroke, force, and ISO 15552 mounting interface.
The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

Where the Airtac SI32 Standard Air Cylinder SI32X800SFA Is Used
Long-Stroke Diversion
Pushes lightweight packages across a transfer lane with its 800 mm travel, relying on the FA flange to hold alignment during rapid 30-800 mm/s actuation.
Compact Tool Feeding
Deploys a small end-effector 800 mm forward into a machining cell, utilizing the 12 mm rod and M10x1.25 thread to drive light tooling loads.
Replacing the Airtac SI32 Standard Air Cylinder SI32X800SFA with the SAI32X800SFA
To replace the SI32X800SFA, order the SAI32X800SFA. Confirm the ISO 15552 interface, 32 mm bore, 800 mm stroke, G1/8 port, FA flange, and the -S magnet for CS1-B/DS1-B switches. Sizing both ways: a 40 mm bore yields 628 N push at 0.5 MPa, while dropping pressure to 0.4 MPa on this 32 mm bore yields about 321 N. Because the stroke is 800 mm, use an external guide to prevent rod bending and side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X800SFA
- ✓ 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 SI32X800SFA FAQ
