This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X140, 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 SID100X140
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X140 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 140mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X140, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X140
The AirTAC SID100X140 is a discontinued ISO 15552 double-rod cylinder where a rod exits both ends, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, 140mm stroke, G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. The direct replacement is the SAID100X140, matching the interface, bore, stroke, and mounting.
Because both faces use the rod-side area, force is equal both ways and the back rod can drive a second tool. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. This non-magnetic SKU cannot take a switch. A plain cylinder does not hold loads on air loss; cushions only decelerate, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID100X140 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X140 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 SID100X140 Is Used
Twin-Tool Machining Station
Uses the extending back rod to drive a secondary clamping fixture, leveraging the equal both ways force to machine parts efficiently.
Anti-Rotation Transfer Gate
The dual rods prevent rotational twist during lateral product diversion on a high-speed packaging line, ensuring smooth stops.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X140 with the SAID100X140
Replace the discontinued SID100X140 directly with the SAID100X140, reusing your existing ISO 15552 FA, LB, or TC mounting hardware and G1/2 port. Size both ways by checking neighbor bores (80mm or 125mm) if you need to adjust the equal both ways force. Choose a double-rod when you need anti-rotation or a back rod to carry a sensor cam. This SKU lacks the -S magnet, so it cannot take a switch. For stroke >=300, verify side-load limits. For load holding on air loss, use an external rod lock or pilot-operated check valve, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X140
- ✓ 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 SID100X140 FAQ
Yes, the SID100X140 is discontinued. The direct replacement is the SAID100X140, which matches the ISO 15552 interface, 100mm bore, 140mm stroke, G1/2 port, and mounting hardware.
It has a G1/2 port and generates equal force both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa.
