This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX230, 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 SI100AX230
The AirTAC Airtac SI100 Standard Cylinder SI100AX230 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 SAI100AX230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX230
The AirTAC SI100AX230 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 230 mm stroke. It features a SUS420J2 stainless piston rod and delivers 3927 N push force at 0.5 MPa via its G1/2 port. The direct replacement is the SAI100AX230, matching the interface, bore, stroke, force and mounting.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure. For load holding, note the air cushion only decelerates; use an external rod lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100AX230 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100AX230 Is Used
Heavy Pressing
Applies the 3927 N push force at 0.5 MPa to seat bearings or form components securely in automated machining lines.
Clamp Fixtures
Holds large workpieces steady during aggressive milling, relying on the 25 mm SUS420J2 stainless rod for corrosion resistance.
Replacing the Airtac SI100 Standard Cylinder SI100AX230 with the SAI100AX230
To replace the SI100AX230, order the SAI100AX230 and verify the ISO 15552 mounting dimensions, G1/2 port, and M20x1.5 rod thread. This non-magnet SKU cannot fit a CS1-B or DS1-B sensor. For sizing, the 100 mm bore yields 3927 N push at 0.5 MPa; dropping to an 80 mm bore gives 2513 N, while increasing pressure to 0.7 MPa provides 5497 N. For this 230 mm stroke, ensure guide alignment to prevent rod bending. If you need held load on air loss, select the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX230
- ✓ 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 SI100AX230 FAQ
Yes, the SI100AX230 is discontinued. The direct replacement is the SAI100AX230. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 230 mm stroke, force, G1/2 port and mounting fixtures.
This double-acting cylinder has a G1/2 port. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
