This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X700LB, 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 SID80X700LB
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X700LB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X700LB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X700LB
The AirTAC SID80X700LB is a discontinued double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, making push and pull force equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore dictates a G3/8 air port, M20x1.5 rod thread, and 36 mm adjustable air cushions. The direct replacement is the SAID80X700LB, sharing the same interface, 700 mm stroke, and LB mounting.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a -S magnet, so it cannot take a magnetic switch. A plain cylinder drifts on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAID80X700LB 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 SID80X700LB Is Used
Dual-End Conveyor Transfer
Drives a pusher from one end while the opposing rod simultaneously retracts a gate, keeping equal force and synchronized motion across the 700 mm travel.
Anti-Rotation Machining Clamp
Uses the twin rods exiting both ends to resist torsional twist during high-vibration metal cutting, maintaining precise clamping pressure.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X700LB with the SAID80X700LB
To replace the discontinued SID80X700LB, specify the SAID80X700LB; it is a direct retaining the ISO 15552 dimensions, LB mount, G3/8 port, and equal-both-ways force. Size both directions by checking neighbor bores: the 63 mm bore yields 1402 N @0.5 MPa, while the 100 mm bore yields 3681 N @0.5 MPa. Choose a double-rod cylinder when you need anti-rotation stability or when the back rod must drive a second mechanism. For the 700 mm stroke, add external guides to prevent rod bending under side loads. This non-magnetic SKU cannot support sensors; for load holding, select the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X700LB
- ✓ 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 SID80X700LB FAQ
Yes, the SID80X700LB is discontinued. The direct replacement is the SAID80X700LB. It shares the same ISO 15552 interface, 80 mm bore, 700 mm stroke, G3/8 port, LB mount, and equal-both-ways force.
Because it is a double-rod cylinder, force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The 80 mm bore fixes the air port at G3/8. It lacks a magnet for sensors.
