This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX750STC, 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 SI32BX750STC
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX750STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 750mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX750STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX750STC
The AirTAC SI32BX750STC is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 750 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. The exact drop-in replacement is the SAI32BX750STC, retaining the same interface, force, and TC trunnion mount.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -B variant uses a SUS304 stainless rod for corrosion resistance, and the -S magnet works with legacy CS1-B/DS1-B sensors. For sizing, a safe working load is ~241 N (60% of [email protected]), yielding a ~20 kg vertical lift with a 2:1 margin.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32BX750STC produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX750STC Is Used
Stainless Rod Actuation
The SUS304 rod resists corrosion in washdown environments, ideal for moving small components over 750 mm in food-grade or moist packaging lines.
Long Stroke Diversion
Provides 750 mm of travel to push products between parallel conveyor belts, utilizing the TC trunnion mount to accommodate frame flex.
Lightweight Vertical Lift
With a safe working load around 241 N, it vertically lifts roughly 20 kg packages with a 2:1 safety margin using stable guide rails.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX750STC with the SAI32BX750STC
To replace the SI32BX750STC, order the SAI32BX750STC. Confirm the ISO 15552 TC trunnion mount, 32 mm bore, 750 mm stroke, G1/8 port, SUS304 rod (-B), and magnet (-S). At 750 mm, prevent rod bending by adding an external guide to manage side loads. If you need more force, the neighbouring 40 mm bore offers 628 N push at 0.5 MPa. Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX750STC
- ✓ 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 SI32BX750STC FAQ
Yes, the SI32BX750STC is discontinued. The exact drop-in replacement is the SAI32BX750STC. It is dimensionally interchangeable per ISO 15552, keeping the same 32 mm bore, 750 mm stroke, G1/8 port, and TC mount.
It uses a G1/8 port. Force output is 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.
