This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX100, 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 SI32BX100
The AirTAC SI32 Standard Air Cylinder SI32BX100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX100
The AirTAC SI32BX100 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 100mm stroke. It delivers 402N push force at 0.5MPa through a G1/8 port. The direct replacement is the SAI32BX100, matching the interface, force, and mounting fixtures.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SKU uses a SUS304 stainless rod (B option) and lacks a magnet, so it cannot take a sensor.

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 SI32BX100 Is Used
Small Part Ejection
Provides reliable 402N push force at 0.5MPa for ejecting light machined components from fixtures.
Package Diverting
Handles 100mm stroke diverting motions on conveyor lines where a SUS304 stainless rod resists moisture.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX100 with the SAI32BX100
To replace the SI32BX100, order the SAI32BX100. Confirm the ISO 15552 mounting interface, 32mm bore, 100mm stroke, G1/8 port, and your specific mounting accessory. Because this SKU lacks a magnet (-S), it cannot accept CS1-B/DS1-B sensors. If you need position sensing, switch to an S-suffix SAI. For sizing, the neighbouring 40mm bore yields 628N push at 0.5MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX100
- ✓ 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 SI32BX100 FAQ
Yes, the SI32BX100 is discontinued. The direct replacement is the SAI32BX100. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 100mm stroke, 402N force, G1/8 port, and mounting interface.
The G1/8 port feeds a 32mm bore yielding 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800 mm/s.
