This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID63X100, 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 SID63X100
The AirTAC Airtac SID Series Double-Rod Cylinder SID63X100 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 SAID63X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID63X100
The AirTAC SID63X100 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SKU has no -S magnet and cannot take a sensor. It is discontinued; the direct replacement is the SAID63X100, matching the 63mm bore, 100mm stroke, G3/8 port, and mounting interface.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A double rod prevents rotation and lets the back rod drive a second tool. A plain cylinder drifts on air loss; the 30mm cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID63X100 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAID63X100 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 SID63X100 Is Used
Twin-Tool Machining Station
Uses the extended back rod to simultaneously drive a secondary cutting head, keeping equal force through the 100mm stroke.
Anti-Rotation Lift Fixture
The dual-rod architecture prevents mechanical twist during vertical workpiece elevation, ensuring strict parallel guidance.
Synchronized Transfer Gate
Shifts a diverting gate from either end of the assembly line, relying on the G3/8 port for rapid 30-800 mm/s actuation.
Replacing the Airtac SID Series Double-Rod Cylinder SID63X100 with the SAID63X100
Replace the discontinued SID63X100 directly with the SAID63X100, reusing the exact ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) and G3/8 port. Size both directions by the equal rod-side area force: 1402 N @0.5, 1962 N @0.7, 2523 N @0.9. If less force is needed, step down to a 50mm bore; if more, step up to 80mm. Choose a double-rod when you need anti-rotation or to drive two tools. This SKU lacks the -S magnet, so it cannot support sensing. For stroke lengths over 300mm, account for side-load deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID63X100
- ✓ 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 SID63X100 FAQ
Yes, the SID63X100 is discontinued. The direct replacement is the SAID63X100, which matches the 63mm bore, 100mm stroke, G3/8 port, and ISO 15552 mounting.
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 fluid port is G3/8, the rod is Ø20mm with an M16x1.5 thread, and speed is 30-800 mm/s.
