This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X150S, 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 SID63X150S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X150S
The AirTAC SID63X150S is a discontinued ISO 15552 double-acting double-rod cylinder featuring a 63mm bore and 150mm stroke. Because a rod exits both ends on one piston, push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The direct replacement is the SAID63X150S, matching the G3/8 port, M16x1.5 rod thread, and 30mm adjustable cushions. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life.
The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. A double rod prevents rotation and lets the back rod carry a sensor cam or drive a second tool. Note that air cushions only decelerate near stroke end; for load holding on air loss, use an external rod lock or the SAIL/BSAI lock variant.

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 SAID63X150S 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 SID63X150S Is Used
Synchronized Tool Driving
Drives two opposing tools simultaneously from a single piston, utilizing the equal both ways force to maintain perfectly balanced machining pressure on both ends.
Anti-Rotation Guiding
Ideal for precision workholding where the dual rod exits prevent rotational play, keeping the guided payload perfectly stable throughout the 150mm travel.
Dual-End Transfer
Transfers parts on a conveyor line using both rod ends to push and retract separate payloads, doubling cycle efficiency without adding extra valves.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X150S with the SAID63X150S
To replace the discontinued SID63X150S, install the direct replacement SAID63X150S, reusing the existing ISO 15552 mounting interface (Basic, FA, LB, or TC). When sizing both ways, verify the equal push/pull force of 1402 N @0.5 MPa is sufficient; if not, step up to the 80mm bore or down to the 50mm bore. A double rod is the right choice when you need anti-rotation stability or want the rear rod to drive a second mechanism. The -S magnet supports legacy CS1-B/DS1-B sensors. For stroke lengths of 300mm or more, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X150S
- ✓ 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 SID63X150S FAQ
Yes, the SID63X150S is discontinued. The direct replacement is the SAID63X150S. It shares the identical ISO 15552 interface, 63mm bore, 150mm stroke, G3/8 port, and mounting dimensions, while adding an upgraded piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port size is G3/8, fixed by the 63mm bore. Speed ranges from 30-800 mm/s.
