This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1500S, 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 SI100X1500S
The AirTAC SI100 Standard Cylinder SI100X1500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1500S
The AirTAC SI100X1500S is a discontinued double-acting ISO 15552 profile cylinder with a 1500 mm stroke. It delivers a push force of 3927 N at 0.5 MPa. The direct replacement is the SAI100X1500S, matching the bore, stroke, force, G1/2 port, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X1500S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1500 mm between conveyor lines using 3927 N of thrust at 0.5 MPa.
Large Assembly Press
Actuates a 1.5 meter fixture travel, relying on the 36 mm adjustable air cushions to decelerate at stroke ends.
Replacing the Airtac SI100 Standard Cylinder SI100X1500S with the SAI100X1500S
To replace the SI100X1500S, order the SAI100X1500S. Verify the ISO 15552 mounting interface, 100 mm bore, 1500 mm stroke, G1/2 port (PT/G/NPT), and mounting accessories. The -S magnet is present for position sensing. Sizing both ways: a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore yields 6136 N. A plain cylinder drifts on air loss as the cushion only decelerates; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 1500 mm, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1500S
- ✓ 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 SI100X1500S FAQ
Yes, the SI100X1500S is discontinued. The direct replacement is the SAI100X1500S. It is dimensionally interchangeable per ISO 15552, keeping the same 100 mm bore, 1500 mm stroke, G1/2 port, and mounting interface.
It features a G1/2 port. The force ratings are: push 3927 N and pull 3681 N at 0.5 MPa; push 5497 N at 0.7 MPa; push 7068 N at 0.9 MPa; with a theoretical max of 801 kgf at 1.0 MPa.
