This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X600S, 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 SI160 Standard Cylinder SI160X600S
The AirTAC SI160 Standard Cylinder SI160X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X600S
The AirTAC SI160X600S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 600 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI160X600S, a direct sharing the same interface, M36x2 rod thread and 50 mm cushions.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked. This -S model carries a piston magnet for CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160X600S Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring up to 14074 N thrust at 0.7 MPa, utilizing the 50 mm adjustable cushions to stop heavy masses smoothly.
Palletized Lifting
Raises 500 kg platform loads in automated warehousing, where the 160 mm bore provides the necessary push force and the 600 mm stroke grants ample vertical travel.
Large Assembly Actuation
Shifts substantial structural components along 600 mm horizontal paths, relying on external guides to manage side-load and prevent rod bending during transit.
Replacing the Airtac SI160 Standard Cylinder SI160X600S with the SAI160X600S
To replace the SI160X600S, order the SAI160X600S direct. Verify the ISO 15552 mounting interface, 160 mm bore, 600 mm stroke, G3/4 port (PT/G/NPT) and your specific mounting accessory. The -S suffix means a magnet is present for CS1-B/DS1-B switches; the SAI uses current AirTAC switches. Neighbouring bores are 125 mm (6136 N @0.5 MPa) and 200 mm (15708 N). A plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify an SAIL/BSAI lock variant. For the 600 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X600S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X600S FAQ
Yes, the SI160X600S is discontinued. The direct replacement is the SAI160X600S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 600 mm stroke, output force, G3/4 port and mounting interface.
The 160 mm bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
