This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X560S, 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 SI100X560S
The AirTAC Airtac SI100 Standard Cylinder SI100X560S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 560mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X560S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X560S
The AirTAC SI100X560S is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 560 mm stroke. Delivering 3927 N push force at 0.5 MPa via a G1/2 port, its direct replacement is the SAI100X560S, sharing the exact same interface, bore, stroke, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The family adds SAIL, SAIF, and BSAI variants the SI lacked. The original -S magnet supports CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches.

Where the Airtac SI100 Standard Cylinder SI100X560S Is Used
Heavy Material Handling
Drives robust conveyor diverters and heavy pallet stops requiring the full 5497 N push force at 0.7 MPa operating pressure.
Large Press Ejection
Ejects heavy formed parts from large industrial presses, utilizing the 36 mm adjustable air cushions to decelerate at stroke end.
Replacing the Airtac SI100 Standard Cylinder SI100X560S with the SAI100X560S
To replace the SI100X560S, order the SAI100X560S: it matches the ISO 15552 mounting dimensions, 100 mm bore, 560 mm stroke, G1/2 port (PT/G/NPT), and M20x1.5 rod thread. Retain your -S magnet specification for position sensing. For sizing, neighbouring bores are 80 mm (2513 N push @0.5) and 125 mm (6136 N push @0.5). Note that a plain cylinder does not hold load on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 560 mm stroke, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X560S
- ✓ 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 SI100X560S FAQ
Yes, the AirTAC SI100X560S is discontinued. The direct replacement is the SAI100X560S. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 560 mm stroke, output force, G1/2 port, and mounting interface.
The G1/2 port bore delivers a push of 3927 N and pull of 3681 N 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. Operating speed is 30-800 mm/s.
