This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX130, 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 SI100AX130
The AirTAC Airtac SI100 Standard Cylinder SI100AX130 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 130mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX130, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX130
The AirTAC SI100AX130 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 130 mm stroke. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a G1/2 port and an SUS420J2 stainless steel piston rod. AirTAC replaced this legacy unit with the SAI100AX130 direct replacement, retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI100AX130 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this SKU lacks a magnet (-S) and cannot accept a sensor. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line.

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 SAI100AX130 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 SI100AX130 Is Used
Heavy-Duty Pressing
Drives robust pressing and forming stations requiring substantial thrust, delivering 5497 N at 0.7 MPa to seat bearings and assemble heavy mechanical components.
Pallet Diversion
Actuates heavy-duty pallet stops and diverter arms on high-throughput packaging lines, utilizing the 130 mm stroke to redirect loads efficiently.
Replacing the Airtac SI100 Standard Cylinder SI100AX130 with the SAI100AX130
To replace the discontinued SI100AX130, order the SAI100AX130. Confirm the ISO 15552 mounting interface, 100 mm bore, 130 mm stroke, G1/2 port (PT/G/NPT thread options), and your specific mounting accessory. Because this SKU lacks a magnet, it cannot accept position sensors; if sensing is needed, specify an SAI model with the -S suffix. For sizing alternatives, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore provides 6136 N. A plain cylinder does not hold load without live air; for load holding, consider the SAIL lock variant, BSAI clamp-lock, or an external pilot check valve. The default carbon steel rod is also available if SUS420J2 stainless is unnecessary.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX130
- ✓ 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 SI100AX130 FAQ
Yes, the SI100AX130 is discontinued. The direct replacement is the AirTAC SAI100AX130. It shares the identical ISO 15552 mounting interface, 100 mm bore, 130 mm stroke, output force, and G1/2 port, fitting directly into existing fixtures without modification.
This double-acting cylinder features a G1/2 port and generates a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N, and 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
