This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X600, 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 SID100X600
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X600
The AirTAC SID100X600 is a double-acting, double-rod ISO 15552 cylinder with a 100mm bore and 600mm stroke. Because a rod exits both ends, the effective piston area is identical in each direction, yielding equal push and pull force (3681N at 0.5MPa). This specific SID model is discontinued; the direct replacement is the SAID100X600, which retains the exact ISO 15552 mounting interface, G1/2 port, M20x1.5 rod thread, and 3681N force. The SAI upgrade also introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life.
With a 600mm stroke, external guides are recommended to prevent rod bending under side loads. This SKU lacks a magnet (-S), so it cannot accept legacy CS1-B/DS1-B sensors. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID100X600 Is Used
Synchronized Workpiece Transfer
Drives two parallel grippers simultaneously from opposite ends of the cylinder, ensuring perfectly synchronized part handling without requiring a separate linkage.
Equal-Force Push and Pull Divert
Diverts items on a line using equal force in both directions, taking advantage of the identical push and pull areas to maintain consistent actuation speed.
Anti-Rotation Registration Stop
Uses the dual-rod geometry to resist torsional twisting during heavy-duty indexing, holding a mechanical stop firmly in place without lateral deflection.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X600 with the SAID100X600
To replace the discontinued SID100X600, install the direct replacement SAID100X600, matching the 100mm bore, 600mm stroke, G1/2 port, and ISO 15552 mounting. Because force is equal both ways, you size both extension and retraction identically; if downscaling, the 80mm bore provides 2268N and the 125mm bore provides 5734N at 0.5MPa. A double-rod design is correct when you need anti-rotation, or when the back rod drives a second tool or carries a sensor cam. Reuse FA, LB, or TC mounts. As this is a non-magnetized SKU, it cannot take switches. Because the 600mm stroke exceeds 300mm, use external guides to manage side loads and prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X600
- ✓ 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 SID100X600 FAQ
Yes, the SID100X600 is discontinued. The direct replacement is the SAID100X600. It shares the same ISO 15552 interface, 100mm bore, 600mm stroke, G1/2 port, and equal both-ways force. The SAI family also adds an upgraded two-piece Y-shaped piston seal for longer life.
Force is equal both ways: 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa. Speed is 30-800mm/s. Air cushions only decelerate near stroke end; they do not hold loads on air loss, so use an external rod lock or SAIL/BSAI variant for holding.
