This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X100S, 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 SID160X100S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X100S
The AirTAC SID160X100S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal. The direct replacement is the SAID160X100S, which retains the 160mm bore, 100mm stroke, G3/4 port, and mounting interface. The SAI family introduces an upgraded piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life.
With a 40mm rod and M36x2 thread, force is equal both ways at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The double-rod design prevents rotation and allows the back rod to carry a sensor cam. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SID Series Double-Rod Cylinder SID160X100S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads from a single piston, utilizing the equal both ways 13194 N @0.7 MPa force to push and pull cutting tools with identical rigidity.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent mechanical rotation during heavy product diversion, ensuring precise lateral transfers without guide binding.
Symmetric Pallet Lift
Lifts palletized loads using both rod ends, where the rear rod carries a sensor cam for mid-stroke positioning while the front rod manages the 480 kg vertical lift load.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X100S with the SAID160X100S
To replace the discontinued SID160X100S, specify the SAID160X100S, which is a direct upgrade keeping the ISO 15552 dimensions, 100mm stroke, and G3/4 port. Size both directions by verifying the equal force of 9425 N @0.5 MPa meets your needs; if a smaller footprint is acceptable, evaluate the 125mm bore (5734 N @0.5 MPa), or step up if higher force is required. A double rod is the right choice when you need anti-rotation stability or want to drive two tools simultaneously. Mounting options include Basic, FA, LB, and TC. Because this is an -S model, it has a built-in magnet for position sensing. For strokes of 300mm or longer, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X100S
- ✓ 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 SID160X100S FAQ
Yes, the SID160X100S is discontinued. The direct replacement is the SAID160X100S, which shares the identical ISO 15552 mounting interface, 160mm bore, 100mm stroke, G3/4 port, and equal both ways force, while adding an upgraded piston seal.
The bore uses a G3/4 air port. Because it is a double-rod cylinder, force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. Note that a plain cylinder does not hold loads on air loss; the 50mm adjustable cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.
