This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X375, 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 SI32X375
The AirTAC SI32 Standard Air Cylinder SI32X375 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 375mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X375, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X375
The AirTAC SI32X375 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 375mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X375. This direct successor matches the exact interface, bore, force and mounting dimensions.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and longevity. Without a -S suffix, this SKU lacks a magnet and cannot host CS1-B/DS1-B sensors. Note that plain cylinders drift without air; use SAIL or BSAI lock variants for holding.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SI32 Standard Air Cylinder SI32X375 Is Used
Bin Push-Off
Provides the 375mm reach needed to eject components from shallow storage bins, utilizing the 20kg vertical lift capacity for smooth gravity-fed removal.
Gate Opening
Suitable for swinging small access doors or vents on machinery enclosures, with the long 375mm stroke allowing full clearance for operator access.
Replacing the Airtac SI32 Standard Air Cylinder SI32X375 with the SAI32X375
To replace the SI32X375, order the SAI32X375. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.), the G1/8 port, and the M10x1.25 rod thread. Because this 375mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load damage. If you need more force than the 402N push at 0.5MPa, step up to a 40mm bore (628N); if less is required, re-evaluate your pressure. This non-magnetic SKU cannot take a sensor. For load-holding without live air, specify the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X375
- ✓ 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 SI32X375 FAQ
Yes, the SI32X375 is end-of-life. The direct replacement is the SAI32X375. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 375mm stroke, G1/8 port, and mounting interface to fit existing fixtures directly.
It features a G1/8 air port. Force output is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
