This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X1100S, 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 SID63X1100S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X1100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X1100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X1100S
The AirTAC SID63X1100S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The bore is 63 mm, the port is G3/8, and it includes an -S magnet for legacy CS1-B/DS1-B sensors. This SID model is discontinued; the direct replacement is the SAID63X1100S, which reuses the same ISO 15552 mounting interface, bore, stroke, and port.
Because both faces use the rod-side area, the equal-both-ways force prevents rod-side drift and allows the back rod to carry a sensor cam. The SAI upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant, as cushions only decelerate.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAID63X1100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID63X1100S Is Used
Equal-Force Transfer
Drives a conveyor pusher with identical push and pull force, preventing drift during bidirectional material handling.
Anti-Rotation Tooling
Powers a machining fixture where the dual rods resist rotational torque and maintain precise tool alignment.
Dual-End Cam Sensing
Uses the rear protruding rod to carry a sensor cam, allowing position confirmation in tight machinery spaces.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X1100S with the SAID63X1100S
To replace the discontinued SID63X1100S, install the direct replacement SAID63X1100S, matching the 63 mm bore, 1100 mm stroke, G3/8 port, and ISO 15552 mounting. Size both directions using the equal force of 1402 N @0.5 MPa; if less force is needed, step down to the 50 mm bore (825 N), or step up to the 80 mm bore (2268 N) for more power. Choose a double-rod cylinder when you need anti-rotation, equal push/pull, or a back-rod sensor cam. Reuse FA, LB, or TC mounts. The -S magnet fits legacy CS1-B/DS1-B switches. For this 1100 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X1100S
- ✓ 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 SID63X1100S FAQ
Yes, the SID63X1100S is discontinued. The direct replacement is the SAID63X1100S, matching the 63 mm bore, 1100 mm stroke, G3/8 port, and ISO 15552 mounting. The SAI family also adds an upgraded piston seal and SAIL/BSAI lock variants.
Force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. Speed is 30-800 mm/s. The cylinder uses a G3/8 port, M16x1.5 rod thread, and 30 mm adjustable cushions. It does not hold loads without live air.
