This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX900, 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 SI160AX900
The AirTAC SI160 Standard Cylinder SI160AX900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX900
The AirTAC SI160AX900 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 900 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a 40 mm SUS420J2 stainless steel rod and a G3/4 port. The direct replacement is the SAI160AX900, matching the bore, stroke, force, port, and ISO 15552 mounting interface exactly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160AX900 Is Used
Heavy Press Systems
Drives large press platens requiring high force, utilizing the 10053 N push capacity at 0.5 MPa for industrial metal forming.
Large Mold Handling
Actuates 900 mm stroke movements to shift heavy injection molds into and out of machining centers.
Replacing the Airtac SI160 Standard Cylinder SI160AX900 with the SAI160AX900
To replace the SI160AX900, order the SAI160AX900. Verify the ISO 15552 mounting interface, the 900 mm stroke, and the G3/4 port. This non-magnetic SKU cannot support position sensing; if switches are needed, select an SAI equivalent with the S suffix. For heavy lifts, neighbouring bores (125 mm or 200 mm) offer different force classes. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. Because the 900 mm stroke is long, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX900
- ✓ 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 SI160AX900 FAQ
Yes, the SI160AX900 is discontinued. The direct replacement is the SAI160AX900. It shares the same ISO 15552 mounting interface, 160 mm bore, 900 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
This double-acting cylinder has a G3/4 port. 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.
