This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX60S, 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 SI100 Standard Cylinder SI100BX60S
The AirTAC Airtac SI100 Standard Cylinder SI100BX60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX60S
The AirTAC SI100BX60S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore, 60mm stroke, and a SUS304 stainless steel rod. Delivering 3927 N push at 0.5 MPa, its direct replacement is the SAI100BX60S, sharing the same G1/2 port, M20x1.5 thread, and mounting interface. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life.
This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. For high heat, Viton H seals raise the temperature limit to 150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100BX60S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100BX60S Is Used
Heavy-Duty Pressing
Drives high-force stamping and forming stations, utilizing the 3927 N thrust at 0.5 MPa to seat bearings or assemble heavy components reliably.
Pallet Lift Gates
Raises and lowers loaded pallet stops in distribution hubs, where the SUS304 rod provides corrosion resistance against humid or washdown environments.
Replacing the Airtac SI100 Standard Cylinder SI100BX60S with the SAI100BX60S
To replace the SI100BX60S, order the SAI100BX60S. Verify the ISO 15552 mounting interface, 60mm stroke, G1/2 port, and the -B SUS304 rod option. The built-in magnet (-S) accepts legacy CS1-B/DS1-B switches, though the SAI replacement family uses current AirTAC switches. If sizing up, the 125mm bore offers 6136 N push at 0.5 MPa; sizing down, the 80mm bore gives 2513 N. A plain cylinder drifts on air loss, so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX60S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100BX60S FAQ
Yes, the SI100BX60S is discontinued. The direct replacement is the SAI100BX60S. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 60mm stroke, G1/2 port, and mounting interface to fit existing fixtures directly.
This double-acting cylinder features a G1/2 air port. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum force of 801 kgf at 1.0 MPa.
