This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X160, 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 SID Series Double-Rod Cylinder SID160X160
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X160
The AirTAC SID160X160 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force. This SKU lacks a magnet (-S), so it cannot accept magnetic switches. The G3/4 air port, M36x2 rod thread, and 50mm cushions are fixed by the 160mm bore. The SID line is discontinued; the direct replacement is the SAID160X160, which reuses the same ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
Because both faces use the identical rod-side area, force is equal both ways: 9425N at 0.5MPa, 13194N at 0.7MPa, and 16964N at 0.9MPa. Note that a plain cylinder drifts on air loss; the adjustable cushion only decelerates near stroke end and does not hold loads. For held loads, use an external rod lock or the SAIL/BSAI lock variants.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X160 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID160X160 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilizing the equal both-ways force to ensure perfectly synchronized cutting cycles.
Anti-Rotation Transfer Gate
Uses the dual exiting rods to mechanically resist torsional twist during heavy lateral product transfers on a high-speed packaging conveyor.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X160 with the SAID160X160
To replace the discontinued SID160X160, install the SAID160X160 directly; it preserves the 160mm bore, 160mm stroke, G3/4 port, and ISO 15552 mounting footprint without bracket changes. Size both directions using the equal-both-ways force (9425N at 0.5MPa); if you need less force, step down to the 125mm bore, or step up to 200mm for more. Choose a double-rod design when you need anti-rotation stability or must drive two tools from one piston. Reuse FA, LB, or TC mounts. Since this SKU lacks the -S magnet, add external sensors if needed. For this 160mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X160
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID160X160 FAQ
Yes, the SID160X160 is discontinued. The direct replacement is the SAID160X160. It shares the same ISO 15552 interface, 160mm bore, stroke, G3/4 port, and equal both-ways force, while adding an upgraded piston seal.
Force is equal both ways: 9425N at 0.5MPa, 13194N at 0.7MPa, and 16964N at 0.9MPa. Operating speed is 30-500mm/s. The cylinder uses a G3/4 port and 50mm adjustable cushions at each end.
