This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X100S, 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 SID63X100S
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID63X100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X100S
The AirTAC SID63X100S is a discontinued double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Because both faces use the rod-side area, 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 SAID63X100S, retaining the 63mm bore, 100mm stroke, G3/8 port, and mounting interface. The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
This bore features a Ø20mm piston rod, M16x1.5 rod-end thread, and 30mm adjustable air cushions at each end. The double-rod design prevents rod rotation and lets the back rod carry a sensor cam or drive a second tool. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID63X100S Is Used
Synchronized Workpiece Transfer
Drives two opposing grippers simultaneously using both extending rods, ensuring perfectly balanced part handling without rotational drift.
Dual-End Sorting Diverter
Uses the equal push and pull force to positively divert products on a conveyor belt in both directions without needing a larger bore.
External Cam Positioning
The rear rod extension carries a sensor cam, allowing external legacy CS1-B/DS1-B switches to confirm mid-stroke positioning independently.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X100S with the SAID63X100S
To replace the discontinued SID63X100S, specify the SAID63X100S, which is a direct swap keeping the ISO 15552 mounting interface, 63mm bore, 100mm stroke, and G3/8 port. Size both directions by the equal force output: this bore delivers 1402 N @0.5 MPa. If you need more force, the neighbouring 80mm bore provides 2268 N @0.5 MPa, while the 50mm bore offers 825 N. A double-rod cylinder is the right choice when you need anti-rotation stability, want the back rod to drive a second mechanism, or require equal push/pull forces. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B sensors (current AirTAC switches are used on the SAI replacement). For stroke lengths of 300mm or greater, verify side-load limits to prevent guide bushing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X100S
- ✓ 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 SID63X100S FAQ
Yes, the SID63X100S is discontinued. The direct replacement is the SAID63X100S. It shares the same ISO 15552 interface, 63mm bore, 100mm stroke, G3/8 port, and mounting options, 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. Operating speed is 30-800 mm/s. The cylinder uses a G3/8 port and features 30mm adjustable air cushions at each end.
