This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX130S, 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 SI100AX130S
The AirTAC Airtac SI100 Standard Cylinder SI100AX130S 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 SAI100AX130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX130S
The AirTAC SI100AX130S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 130mm stroke. Delivering 3927 N push force at 0.5 MPa through a G1/2 port, it is replaced by the SAI100AX130S. This direct upgrade shares identical ISO 15552 mounting dimensions, bore, stroke, and force.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. Your -A suffix specifies a SUS420J2 stainless rod, and -S adds a magnet for CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100AX130S Is Used
Heavy-Duty Pressing
Drives robust stamping and forming actions requiring up to 3927 N of thrust at 0.5 MPa.
Pallet Diversion
Actuates heavy pallet stops and routing gates in high-throughput distribution centers.
Mold Clamping
Secures industrial molds and heavy fixtures securely during manufacturing operations.
Replacing the Airtac SI100 Standard Cylinder SI100AX130S with the SAI100AX130S
To replace the SI100AX130S, order the SAI100AX130S. Verify the ISO 15552 mounting interface, 130mm stroke, G1/2 port, and your specific -A SUS420J2 stainless rod and -S magnet options. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. Since this plain cylinder drifts on air loss, use an external rod lock or pilot check valve for load holding. The 130mm stroke avoids severe rod-bending side-load risks, but always guide the load. The SAI family also adds SAIL, SAIF, and BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX130S
- ✓ 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 SI100AX130S FAQ
Yes, the SI100AX130S is discontinued. The direct replacement is the SAI100AX130S. It shares the same ISO 15552 mounting interface, 100mm bore, 130mm stroke, output force, G1/2 port, and SUS420J2 stainless rod material, fitting existing fixtures perfectly.
The G1/2 port bore 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 max of 801 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 36mm adjustable cushion.
