This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X900, 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 SID160X900
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X900 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 SAID160X900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X900
The AirTAC SID160X900 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. This 160 mm bore unit features a 40 mm piston rod, a G3/4 air port, an M36x2 rod-end thread, and 50 mm adjustable air cushions at each end. As a legacy product, this SID model is discontinued and is replaced by the direct replacement SAID160X900, which shares the exact ISO 15552 mounting interface, bore, stroke, and porting.
The SAI replacement family introduces an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life, alongside new SAIL and BSAI lock variants absent from the SI line. Because this specific SKU lacks a magnet, it cannot take a magnetic switch. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID160X900 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads from a single cylinder, utilising the equal both-ways force to deliver 9425 N @0.5 MPa cutting pressure in both directions.
Anti-Rotation Transfer Gate
Uses the double-rod architecture to prevent mechanical rotation during a 900 mm transfer stroke, ensuring precise alignment without external guides.
Symmetric Load Shifter
Shifts heavy pallets symmetrically by attaching the load to both rod ends, balancing the 13194 N @0.7 MPa thrust across the structure.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X900 with the SAID160X900
To replace the discontinued SID160X900, install the direct replacement SAID160X900, which matches the ISO 15552 mounting interface, 160 mm bore, 900 mm stroke, and G3/4 port. When sizing both ways, verify your force requirements against the equal push/pull output of 9425 N @0.5 MPa, 13194 N @0.7 MPa, or 16964 N @0.9 MPa, stepping to neighbouring bores if a different capacity is needed. A double rod is the right choice when you need anti-rotation stability, want to drive two tools from one cylinder, or require a back rod to carry a sensor cam. Mounting options include Basic, FA, LB, and TC styles. This SKU has no -S magnet and cannot accept a sensor. Because the 900 mm stroke is long, account for side-load and rod-bending forces by using external guides to support the rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X900
- ✓ 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 SID160X900 FAQ
Yes, the AirTAC SID160X900 is discontinued. The direct replacement is the SAID160X900, which shares the same ISO 15552 interface, 160 mm bore, 900 mm stroke, G3/4 port, and equal both-ways force.
Because it is a double-rod cylinder, the push and pull force are equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, the rod thread is M36x2, and it operates at 30-500 mm/s.
