This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X300SCB, 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 SI160X300SCB
The AirTAC SI160 Standard Cylinder SI160X300SCB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X300SCB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X300SCB
The AirTAC SI160X300SCB is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 300mm stroke. It delivers a push force of 10053 N at 0.5 MPa through its G3/4 port. AirTAC replaced this legacy unit with the SAI160X300SCB, a direct replacement retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50mm adjustable cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line. Your SI160X300SCB includes a piston magnet for legacy CS1-B/DS1-B sensors, which the SAI swaps for current AirTAC switches.

Where the Airtac SI160 Standard Cylinder SI160X300SCB Is Used
Heavy Press Actuation
Drives large stamping or forming presses requiring 10053 N of push force at 0.5 MPa, utilizing the 300mm stroke to fully cycle heavy tooling.
Large Mold Transfer
Shifts substantial injection molds or industrial fixtures between stations, relying on the rigid CB clevis mount to absorb high dynamic moments.
Replacing the Airtac SI160 Standard Cylinder SI160X300SCB with the SAI160X300SCB
To replace the SI160X300SCB, order the SAI160X300SCB. Verify your CB clevis mounting accessory, the G3/4 port, and the -S magnet requirement. If downsizing, a 125mm bore yields 6136 N push at 0.5 MPa; if upsizing, a 200mm bore provides 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock or pilot check valve, or specify an SAIL/BSAI variant. Because the 300mm stroke can induce rod bending under side loads, ensure external guides are fitted to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X300SCB
- ✓ 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 SI160X300SCB FAQ
Yes, the SI160X300SCB is discontinued. The direct replacement is the AirTAC SAI160X300SCB. It is dimensionally interchangeable per ISO 15552, matching the 160mm bore, 300mm stroke, CB mounting, and G3/4 port for a seamless fixture swap.
This double-acting cylinder features a G3/4 air port and M36x2 rod thread. It generates a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa push is 14074 N, at 0.9 MPa it is 18095 N, and the theoretical maximum is 2050 kgf at 1.0 MPa.
