This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X600, 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 SID80X600
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X600
The AirTAC SID80X600 is a discontinued ISO 15552 double-acting double-rod cylinder where a rod exits both ends, ensuring force is equal both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The direct replacement is the SAID80X600, matching the 80mm bore, 600mm stroke, G3/8 port, and mounting interface. The SAI family improves longevity with an upgraded two Y-shaped one-way piston seal and introduces SAIL and BSAI lock variants absent in the legacy SI line.
Because both faces use the identical rod-side area, this SKU provides anti-rotation stability and lets the back rod drive a second tool. With no -S suffix, this cylinder cannot accept a magnetic switch.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAID80X600 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 SID80X600 Is Used
Twin-Tool Machining Station
Uses the protruding back rod to drive a secondary deburring tool, maintaining equal both-ways force for synchronized machining operations.
Anti-Rotation Transfer Gate
Employs the double-rod architecture to prevent mechanical twist during rapid 600mm transfers, ensuring smooth material flow without binding.
Vertical Lift Fixture
Lifts balanced fixtures up to 116 kg using the equal pull force, relying on external guides to handle side-load over the long 600mm stroke.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X600 with the SAID80X600
To replace the discontinued SID80X600, install the direct replacement SAID80X600, reusing the exact ISO 15552 mounting interface and G3/8 port. Size both ways by checking the equal both-ways force against neighboring bores: the 63mm bore yields 1402 N @0.5 MPa, while the 100mm bore yields 3681 N @0.5 MPa. A double rod is right when you need anti-rotation resistance or a back rod to mount a sensor cam. Reuse FA, LB, or TC mounts. As this is a non-magnetized SKU, it cannot take a switch. For the 600mm stroke, add external guides to prevent rod bending under side-load. Note that air cushions only decelerate; for load holding without live air, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X600
- ✓ 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 SID80X600 FAQ
Yes, the SID80X600 is discontinued. The direct replacement is the SAID80X600, which matches the ISO 15552 mounting interface, 80mm bore, 600mm stroke, G3/8 port, and equal both-ways force.
The SID80X600 features a G3/8 air port and delivers equal force both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It operates at 30-800 mm/s with a 36mm adjustable cushion at each end.
