This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X900, 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 SID80X900
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X900
The AirTAC SID80X900 is a double-acting, double-rod ISO 15552 cylinder with a 900 mm stroke. Because a rod exits both ends, the push and pull forces are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This model is discontinued; the direct replacement is the SAID80X900, retaining the 80 mm bore, G3/8 port, M20x1.5 rod thread, and 36 mm cushions. The SAI upgrade uses a two-piece Y-shaped piston seal for lower start-up pressure and longer life.
With equal both-ways force, the back rod can carry a sensor cam or drive two tools with anti-rotation stability. This SKU lacks a magnet (-S), so it cannot take a switch. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Where the Airtac SID Series Double-Rod Cylinder SID80X900 Is Used
Dual-Tool Transfer
Drives two opposing grippers simultaneously on a conveyor line, utilizing the equal push and pull force on both rod ends to maintain balanced part handling.
Anti-Rotation Machining Clamp
Secures a workpiece from both sides during milling. The double-rod construction prevents piston rotation, ensuring the clamp jaws remain perfectly aligned.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X900 with the SAID80X900
To replace the discontinued SID80X900, install the direct replacement SAID80X900, which matches the ISO 15552 mounting interface, bore, stroke, and G3/8 port. When sizing both ways, verify the equal force fits your load, or step to neighbouring bores (63 mm or 100 mm) for different thrust. A double rod is right when you need equal push/pull force, anti-rotation stability, or a back rod for a sensor cam. Reuse FA, LB, or TC mounts. This SKU has no -S magnet and cannot support sensors. For the 900 mm stroke, add external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X900
- ✓ 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 SID80X900 FAQ
Yes, the SID80X900 is discontinued. The direct replacement is the SAID80X900, which shares the same ISO 15552 interface, 80 mm bore, 900 mm stroke, G3/8 port, and mounting options. The SAI family also adds upgraded piston seals and lock variants.
The double-rod design provides equal force both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The air port is G3/8, the rod thread is M20x1.5, and it features 36 mm adjustable cushions at each end. Speed range is 30-800 mm/s.
