This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X290S, 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 SI160X290S
The AirTAC SI160 Standard Cylinder SI160X290S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 290mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X290S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X290S
The AirTAC SI160X290S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 290 mm stroke. It delivers a thrust of 10053 N at 0.5 MPa, utilizing a 40 mm carbon steel rod and G3/4 port. AirTAC replaced this legacy unit with the SAI160X290S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL and BSAI lock variants absent in the SI line, and the original -S magnet on this unit supports legacy CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160X290S Is Used
Heavy Press Clamping
Generates up to 18095 N at 0.9 MPa to secure large metal castings or heavy assemblies during machining and pressing operations.
Industrial Stamping
Provides the robust linear force required for stamping heavy-gauge materials, utilizing the 50 mm adjustable air cushions to decelerate at stroke ends.
Replacing the Airtac SI160 Standard Cylinder SI160X290S with the SAI160X290S
To replace the SI160X290S, order the SAI160X290S and confirm the ISO 15552 mounting interface, 290 mm stroke, G3/4 port, and your mounting accessory (LB, FA, TC, etc.). The -S suffix means a piston magnet is present for CS1-B/DS1-B switches; the SAI replacement uses current AirTAC switches. For sizing, a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. At 0.7 MPa this 160 mm bore outputs 14074 N. Because the stroke is 290 mm, ensure adequate guiding to prevent rod bending and side loads. A plain cylinder drifts without live air; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X290S
- ✓ 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 SI160X290S FAQ
Yes, the AirTAC SI160X290S is discontinued. The direct replacement is the SAI160X290S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 290 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
