This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X600S, 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 SID160X600S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X600S
The AirTAC SID160X600S is a discontinued ISO 15552 double-rod, double-acting cylinder. A 40mm rod exits both ends on one piston, meaning both faces use the rod-side area, so push and pull force are equal at 9425N @0.5MPa, 13194N @0.7MPa, and 16964N @0.9MPa. It features a G3/4 port, M36x2 rod thread, and 50mm adjustable cushions. The direct replacement is the SAID160X600S, sharing the exact bore, stroke, and mounting interface.
The SAI upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For double-rod benefits, the back rod can carry a sensor cam while the front drives a tool, offering anti-rotation stability. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches.

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 SAID160X600S 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 SID160X600S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, ensuring perfectly synchronized cutting cycles with equal push and pull force.
Anti-Rotation Transfer Unit
Uses the dual-rod geometry to prevent mechanical twist during long-stroke part transfers, maintaining precise alignment without external guides.
Vertical Lift Elevator
Lifts heavy pallets vertically, leveraging the equal both-ways force to raise and lower loads smoothly while the rear rod actuates a cam sensor.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X600S with the SAID160X600S
To replace the discontinued SID160X600S, use the SAID160X600S direct, keeping the identical ISO 15552 mounting interface, 600mm stroke, and equal-both-ways force. When sizing both ways, verify the 9425N @0.5MPa output fits your load, or step to neighbouring bores like 125mm or 200mm. A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. Reuse FA, LB, or TC mounts. The -S magnet enables legacy CS1-B/DS1-B sensors. For this 600mm stroke, add external guides to prevent rod-bending under side-load. A plain cylinder does not hold loads on air loss; cushions only decelerate, so use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X600S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
