This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X165S, 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 SID100X165S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X165S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 165mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X165S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X165S
The AirTAC SID100X165S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, so push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This bore 100 mm model has a Ø25 mm piston rod, M20x1.5 rod-end thread, G1/2 air port, and 36 mm adjustable air cushions at each end. The SID line is discontinued; the direct replacement is the SAID100X165S, which adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because the second rod can carry a sensor cam or drive two tools while resisting rotation, this configuration suits symmetrical work. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end. For held loads, use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock 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 SID100X165S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from one piston, utilizing the equal both ways force to ensure balanced cutting or clamping pressure on both ends.
Symmetrical Transfer Unit
Transfers workpieces across a conveyor using both rod ends, with the second rod carrying a sensor cam to confirm position without adding external trackers.
Anti-Rotation Lift Assembly
Lifts vertically using the twin rods to prevent mechanical rotation, keeping the payload stable through the full 165 mm travel without external guides.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X165S with the SAID100X165S
To replace the discontinued SID100X165S, specify the SAID100X165S; it preserves the ISO 15552 mounting interface, 100 mm bore, 165 mm stroke, G1/2 port, and equal both ways force. Size both directions by force: if 5153 N @0.7 MPa is insufficient, step up to bore 125, or drop to bore 80 if 2268 N @0.5 is enough. A double rod is right when you need anti-rotation, a back rod for a sensor cam, or to drive two tools. Mounting uses Basic, FA, LB, or TC (no FB/CA/CB/CR). The -S magnet enables switches. For this 165 mm stroke side-load is low, but for strokes >=300 mm confirm guide tolerance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X165S
- ✓ 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 SID100X165S FAQ
Yes, the SID100X165S is discontinued. The direct replacement is the SAID100X165S. It shares the same ISO 15552 interface, 100 mm bore, 165 mm stroke, G1/2 port, and mounting, but adds an upgraded piston seal.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Speed is 30-800 mm/s. It features a Ø25 mm rod, M20x1.5 thread, and 36 mm adjustable cushions.
