This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X1000S, 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 SID63X1000S
The AirTAC SID Series Double-Rod Cylinder SID63X1000S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X1000S
The AirTAC SID63X1000S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force in both directions (1402 N at 0.5 MPa). This 63 mm bore, 1000 mm stroke model is discontinued; the direct replacement is the SAID63X1000S, reusing the same G3/8 port, M16x1.5 rod thread, and 30 mm adjustable cushions.
The SAI upgrade features a two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors.

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 SAID63X1000S 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 SID63X1000S Is Used
Inline Push-Power Transfer
Drives a conveyor divert gate from both ends, utilizing the equal push and pull force to ensure consistent actuation across the 1000 mm travel without directional power loss.
Dual-Tool Machining Station
Mounts a machining head on the primary rod and a sensor cam on the rear rod, using the double-rod geometry to track exact tool position while maintaining anti-rotation stability.
Vertical Lift Fixture
Lifts a 71 kg workpiece vertically using the 1402 N @0.5 MPa force, relying on the equal both-ways power to raise and lower the fixture smoothly while an external guide absorbs side loads.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X1000S with the SAID63X1000S
To replace the discontinued SID63X1000S, install the direct replacement SAID63X1000S, which matches the ISO 15552 mounting interface, 1000 mm stroke, and 1962 N equal-both-ways force at 0.7 MPa. If sizing a new unit, evaluate neighbouring bores (50 mm or 80 mm) to optimize the equal push/pull force. A double-rod design is correct when you need anti-rotation stability, or when the back rod carries a sensor cam. Reuse FA, LB, or TC mounts. The -S suffix provides a magnet for legacy CS1-B/DS1-B switches. For this 1000 mm stroke, use external guide rails to prevent rod bending and side-load damage. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X1000S
- ✓ 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 SID63X1000S FAQ
Yes, the SID63X1000S is discontinued. The direct replacement is the SAID63X1000S. It shares the identical ISO 15552 interface, 63 mm bore, 1000 mm stroke, G3/8 port, and equal both-ways force. The SAI family also adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
Because it is a double-rod cylinder, the push and pull forces are equal both ways: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The operating speed is 30-800 mm/s. The cylinder uses a G3/8 air port and features 30 mm adjustable air cushions at both ends.
