This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1350S, 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 SI160X1350S
The AirTAC SI160 Standard Cylinder SI160X1350S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1350mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1350S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1350S
The AirTAC SI160X1350S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1350 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X1350S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life.
The original SI series lacked integrated lock variants, but the SAI family adds SAIL, SAIF, and BSAI options. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI replacement uses current AirTAC switches. A Viton H seal option raises the operating temperature to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X1350S Is Used
Heavy Stamp Press Feed
Drives heavy material handling arms in stamping lines, utilizing the 14074 N push force at 0.7 MPa to move large metal blanks into the press bed.
Palletizer Lowerator
Lowers heavy palletized loads over the 1350 mm travel, requiring external guide rails to prevent rod bending during the long vertical descent.
Automated Assembly Transfer
Shifts heavy subassemblies between workstations, taking advantage of the 512 kg vertical lift capacity to manage substantial fixture weights.
Replacing the Airtac SI160 Standard Cylinder SI160X1350S with the SAI160X1350S
To replace the SI160X1350S, order the SAI160X1350S. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC), the 160 mm bore, 1350 mm stroke, G3/4 port, and the -S magnet requirement. If downsizing, neighbouring bores like 125 mm offer 6136 N push at 0.5 MPa, while 200 mm yields 15708 N. Because this is a 1350 mm stroke, external guides are strongly recommended to prevent rod bending and excessive side loads. A plain cylinder does not hold load on air loss; the 50 mm adjustable cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1350S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
