This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X100S, 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 SID80X100S
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X100S
The AirTAC SID80X100S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force remain 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 SAID80X100S. It shares the same 80mm bore, 100mm stroke, G3/8 port, M20x1.5 rod thread, and 36mm adjustable cushions. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure.
A second rod prevents rotation and can carry a sensor cam for the built-in -S magnet (legacy CS1-B/DS1-B switches). Note that air cushions only decelerate; for load holding without live air, use an external rod lock or SAIL/BSAI variant.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID80X100S Is Used
Gripper Cam Actuation
Drives two opposing tools simultaneously from one piston, utilising the equal both-ways force to maintain balanced gripping pressure on precision parts.
Edge Guide Mechanism
The twin-rod anti-rotation特性 keeps the web material aligned without lateral twisting, ensuring consistent tracking during high-speed feed operations.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X100S with the SAID80X100S
To replace the discontinued SID80X100S, install the SAID80X100S directly—it preserves the ISO 15552 mounting interface, 100mm stroke, and equal both-ways force. When sizing both ways, verify if the 3175 N @0.7 MPa output fits your process, or step to neighbouring bores (63mm or 100mm) for different force profiles. A double rod is right when you need anti-rotation or a back-end sensor cam. Mount via FA, LB, or TC brackets, and retain the -S magnet option. For strokes >=300mm, ensure adequate side-load guidance to prevent seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X100S
- ✓ 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 SID80X100S FAQ
Yes, the SID80X100S is discontinued. The direct replacement is the SAID80X100S, which maintains the same ISO 15552 interface, bore, stroke, G3/8 port, and equal both-ways force.
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 fixed air port size for the 80mm bore is G3/8, with a 25mm rod and M20x1.5 thread.
