This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX200, 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 SI100AX200
The AirTAC Airtac SI100 Standard Cylinder SI100AX200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX200
The AirTAC SI100AX200 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 200mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa, operating through a G1/2 port. This specific SKU features a SUS420J2 stainless steel piston rod (the -A option) for corrosion resistance, but because it lacks the -S suffix, it cannot accept a magnetic position switch.
AirTAC replaced this legacy unit with the SAI100AX200. The SAI is a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, output force, port and accessories. The upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life.

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 SAI100AX200 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 SI100AX200 Is Used
Heavy-Duty Pressing
Drives robust clamping and pressing actions requiring up to 3927 N of push force at 0.5 MPa, utilizing the SUS420J2 stainless rod in washdown manufacturing zones.
Automated Diversion
Pushes heavy product loads across conveyor belts using the 7068 N available at 0.9 MPa, with the adjustable 36mm cushion absorbing end-of-stroke impact.
Replacing the Airtac SI100 Standard Cylinder SI100AX200 with the SAI100AX200
To replace the SI100AX200, order the SAI100AX200. Verify your existing fixture's ISO 15552 mounting interface, the G1/2 air port, and your rod-end thread (M20x1.5). Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if you require position feedback, select an SAI model with the S suffix. The 100mm bore yields 3927 N push at 0.5 MPa; if you need less force, a neighbouring 80mm bore provides 2513 N. For higher loads, the 125mm bore offers 6136 N. Note that a plain cylinder drifts on air loss—the 36mm adjustable air cushion only decelerates near stroke end. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX200
- ✓ 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 SI100AX200 FAQ
Yes, the SI100AX200 is discontinued. The direct replacement is the SAI100AX200. It shares the identical ISO 15552 mounting interface, 100mm bore, 200mm stroke, G1/2 port, and output force, fitting directly into your existing fixtures.
At 0.5 MPa it provides 3927 N push and 3681 N pull. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
