This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X260, 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 SI160X260
The AirTAC SI160 Standard Cylinder SI160X260 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 260mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X260, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X260
The AirTAC SI160X260 is a discontinued double-acting ISO 15552 profile cylinder, delivering a thrust of 10053 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAI160X260, a direct alternative retaining the exact 160mm bore, 260mm stroke, G3/4 port, and ISO 15552 mounting interface.
This SKU lacks a magnet, so it cannot accept position switches. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL/BSAI lock variants the SI lacked.

Where the Airtac SI160 Standard Cylinder SI160X260 Is Used
Heavy Press Clamping
Generates 14074N at 0.7MPa to secure large metal castings during machining operations.
Stamping Press Feed
Moves heavy blanks into forming dies, utilizing the 50mm adjustable cushions to halt the 160mm bore safely.
Industrial Automation
Drives robust 260mm stroke mechanisms in heavy-duty assembly lines requiring massive output force.
Replacing the Airtac SI160 Standard Cylinder SI160X260 with the SAI160X260
To replace the SI160X260, order the SAI160X260 and verify the ISO 15552 mounting interface, 260mm stroke, and G3/4 port. Because this non-magnet SKU cannot take a sensor, confirm if you need a current AirTAC switch for position feedback. The 40mm rod and M36x2 thread must match your mechanics. Operating at 30-500 mm/s, it yields 10053N push at 0.5MPa; if undersized, the 200mm bore offers more force. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding, specify an external pilot check valve or the SAIL/BSAI lock variant. For this 260mm stroke, ensure guide alignment to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X260
- ✓ 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 SI160X260 FAQ
Yes, the AirTAC SI160X260 is discontinued. The direct replacement is the SAI160X260. It is dimensionally interchangeable per ISO 15552, keeping the same 160mm bore, 260mm stroke, G3/4 port, and mounting fixtures.
The bore is 160mm with a G3/4 port. The force output is 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a maximum theoretical force of 2050kgf at 1.0MPa.
