This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X600SN, 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 SI100X600SN
The AirTAC Airtac SI100 Standard Cylinder SI100X600SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X600SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X600SN
The AirTAC SI100X600SN is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 600mm stroke. It delivers 3927N push at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X600SN, matching the bore, stroke, force, port and ISO 15552 mounting interface exactly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. The NBR seal handles -20 to +70C, with Viton H available.

Where the Airtac SI100 Standard Cylinder SI100X600SN Is Used
Pallet Diversion
Actuates heavy lane diverters for full pallets, utilizing the 3927N push force to shift loads smoothly across high-throughput packaging lines.
Vertical Lift Gate
Raises and lowers 200kg mezzanine safety gates using the 600mm stroke, relying on external guides to prevent rod bending over the long travel.
Press Ejection
Ejects formed metal parts from 100-ton presses, absorbing end-of-stroke impact with the 36mm adjustable air cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X600SN with the SAI100X600SN
To replace the SI100X600SN, order the SAI100X600SN: it drops into existing fixtures via the identical ISO 15552 mounting interface, keeping the 100mm bore, 600mm stroke, G1/2 port and M20x1.5 rod thread. The S suffix means it has a piston magnet for CS1-B/DS1-B switches (the SAI uses current AirTAC switches); the N suffix denotes the NBR seal. If sizing down, the 80mm bore yields 2513N push at 0.5MPa; sizing up to 125mm provides 6136N. For this 600mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so use a pilot check valve or SAIL/BSAI lock variant to hold loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X600SN
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
