This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX230, 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 SI100BX230
The AirTAC Airtac SI100 Standard Cylinder SI100BX230 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 230mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX230
The AirTAC SI100BX230 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore, 230mm stroke, and a SUS304 stainless steel piston rod. Delivering 3927 N push and 3681 N pull at 0.5 MPa via a G1/2 port, its direct replacement is the SAI100BX230. This successor maintains the identical mounting interface, bore, stroke, force, and port size, fitting existing fixtures seamlessly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note that this specific SKU lacks a magnet (-S), so it cannot accept position sensors. The cushion only decelerates; it does not hold loads on air loss.

Where the Airtac SI100 Standard Cylinder SI100BX230 Is Used
Heavy Press Clamping
Secures large metal workpieces in machining centers, utilizing the 3927 N push force and SUS304 rod to resist coolant corrosion.
Pallet Diverting
Actuates heavy-duty routing gates on high-throughput packaging lines, handling the 200 kg vertical lift capacity safely.
Automated Storage Lifts
Drives vertical elevation platforms in automated retrieval systems, requiring external check valves to hold loads securely.
Replacing the Airtac SI100 Standard Cylinder SI100BX230 with the SAI100BX230
To replace the SI100BX230, order the SAI100BX230. Confirm the ISO 15552 mounting interface, the 100mm bore, the 230mm stroke (a non-standard length), and the G1/2 port. Retain your original mounting accessory and note the SUS304 (-B) rod. Because this SKU lacks a magnet, it cannot support legacy CS1-B/DS1-B sensors. For sizing, neighboring bores offer different forces: an 80mm bore provides 2513 N push, while a 125mm bore yields 6136 N at 0.5 MPa. Since this is a non-standard 230mm stroke, ensure external guides prevent rod bending under side loads. For load holding on air loss, add an external rod lock or pilot check valve, or specify the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX230
- ✓ 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 SI100BX230 FAQ
Yes, the SI100BX230 is discontinued. The direct replacement is the SAI100BX230. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 230mm stroke, 3927 N force, G1/2 port, and mounting interface.
This double-acting cylinder uses a G1/2 port. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. It operates at 30-800 mm/s.
