This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X230, 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 SI160X230
The AirTAC SI160 Standard Cylinder SI160X230 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 230mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X230
The AirTAC SI160X230 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 230 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X230. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting hardware.
The SAI160X230 upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot take a sensor; legacy -S types used CS1-B/DS1-B switches.

Where the Airtac SI160 Standard Cylinder SI160X230 Is Used
Heavy Stamping
Drives large press dies and heavy metal forming fixtures requiring 10053 N of thrust at 0.5 MPa.
Pallet Handling
Indexes loaded pallets and heavy materials along conveyors with a robust 40 mm piston rod.
Automated Welding
Actuates substantial welding guns and heavy-duty clamps in automotive body-in-white assembly lines.
Replacing the Airtac SI160 Standard Cylinder SI160X230 with the SAI160X230
To replace the SI160X230, order the SAI160X230. Confirm the ISO 15552 interface, 160 mm bore, 230 mm stroke, G3/4 port (PT/G/NPT threads), and mounting accessory. Size both ways: neighbouring bores are 125 mm (6136 N [email protected]) and 200 mm (15708 N [email protected]). This plain cylinder drifts on air loss as the 50 mm cushion only decelerates; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for held loads. For 230 mm strokes, guide the load to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X230
- ✓ 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 SI160X230 FAQ
Yes, the SI160X230 is discontinued. The direct replacement is the SAI160X230. It shares the exact ISO 15552 mounting interface, 160 mm bore, 230 mm stroke, output force, G3/4 port, and accessories, fitting existing fixtures perfectly.
The 160 mm bore features a G3/4 port, a 40 mm rod, and a 50 mm cushion. It 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. Speed is 30-500 mm/s.
