This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X150S, 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 SID80X150S
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X150S
The AirTAC SID80X150S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It features an 80mm bore, G3/8 air port, M20x1.5 rod thread, 36mm adjustable cushions, and a -S piston magnet for legacy CS1-B/DS1-B switches. The direct replacement is the SAID80X150S, which reuses the same ISO 15552 mounting interface, bore, stroke, and port.
Because both faces use the rod-side area, this cylinder delivers equal both-ways force, providing anti-rotation stability and allowing the back rod to carry a sensor cam or drive two tools simultaneously. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note that a plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID80X150S Is Used
External Gripper Actuation
Drives opposing gripper jaws simultaneously from a single piston, ensuring perfectly synchronized and equal clamping force in both directions.
Dual-Side Transfer Pusher
Uses both extending rods to push pallets from either side of a conveyor lane, maintaining straight tracking without rotational drift.
Web Edge Guiding
Steers material webs via the rear rod connection while the front rod maintains an equal opposing tension, preventing skew during high-speed feed.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X150S with the SAID80X150S
To replace the discontinued SID80X150S, specify the SAID80X150S; it is a direct retaining the ISO 15552 interface, 80mm bore, 150mm stroke, G3/8 port, and -S magnet. Size both ways using the equal force ratings (2268 N @0.5 MPa, 3175 N @0.7 MPa, 4082 N @0.9 MPa). If you need less force, step down to the 63mm bore (1402 N @0.5 MPa); for more, step up to the 100mm bore (3681 N @0.5 MPa). Choose a double-rod design when you need anti-rotation resistance or must drive two tools from one piston. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet for position sensing. For strokes of 300mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X150S
- ✓ 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 SID80X150S FAQ
Yes, the SID80X150S is discontinued. The direct replacement is the SAID80X150S. It shares the identical ISO 15552 mounting interface, 80mm bore, 150mm stroke, G3/8 port, and equal both-ways force, while adding an upgraded Y-shaped piston seal for longer life.
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 bore is 80mm with a G3/8 air port, a 25mm rod, M20x1.5 rod thread, and 36mm adjustable cushions at each end. Speed range is 30-800 mm/s.
