This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X700STC, 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 SI32X700STC
The AirTAC SI32 Standard Air Cylinder SI32X700STC 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 SAI32X700STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X700STC
The AirTAC SI32X700STC is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 700 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32X700STC, a direct replacement retaining the exact ISO 15552 mounting interface, stroke, force, and TC trunnion mount.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For applications needing load holding on air loss, the new SAI family offers SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI32 Standard Air Cylinder SI32X700STC Is Used
Long-Stroke Diversion
Drives 700 mm sorting gates on packaging lines where the 402 N push force easily overcomes flap friction.
Vertical Lift Stops
Raises lightweight 20 kg tote stops at distribution hubs, utilizing the TC trunnion mount for pivot alignment.
Light Part Ejection
Pushes machined aluminum components out of a CNC enclosure, benefiting from the 30-800 mm/s speed range.
Replacing the Airtac SI32 Standard Air Cylinder SI32X700STC with the SAI32X700STC
To replace the SI32X700STC, order the SAI32X700STC. Confirm the ISO 15552 TC trunnion mounting, 32 mm bore, 700 mm stroke, G1/8 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). Sizing context: at 0.5 MPa this bore yields 402 N push and 345 N pull. If more force is needed, the neighboring 40 mm bore provides 628 N push. Because this is a 700 mm stroke, external guides are recommended to prevent rod bending and side-load wear. A plain cylinder drifts without air; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X700STC
- ✓ 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 SI32X700STC FAQ
Yes, the SI32X700STC is discontinued. The direct replacement is the SAI32X700STC. It shares the same ISO 15552 mounting interface, 32 mm bore, 700 mm stroke, G1/8 port, and TC trunnion mount, fitting directly into existing fixtures.
It features 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 maximum of 82 kgf at 1.0 MPa.
