This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X80, 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 SID32X80
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X80
The AirTAC SID32X80 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force is equal both ways (345 N at 0.5 MPa). Because both faces use the identical rod-side area, you never quote a larger single-rod push value. This 32 mm bore unit features a 12 mm piston rod, M10x1.25 rod-end thread, and a G1/8 air port. This SID model is discontinued; the direct replacement is the SAID32X80, which reuses the same ISO 15552 mounting interface, bore, stroke, and porting.
The SAI upgrade path introduces an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet (no -S suffix) and cannot take a magnetic switch. A plain cylinder does not hold its load on air loss; the air cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID32X80 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAID32X80 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 SID32X80 Is Used
Synchronized Tool Driving
Drive two separate operations simultaneously from one piston, using the opposing rod ends to actuate distinct mechanisms without adding a second cylinder.
Anti-Rotation Guidance
Prevent piston rotation during travel in precision indexing tasks by leveraging the dual-rod architecture for inherent mechanical stability.
Equal Push/Pull Diverting
Apply identical 345 N force in both directions on a diverting arm, ensuring consistent product routing regardless of extension or retraction direction.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X80 with the SAID32X80
To replace the discontinued SID32X80, swap in the SAID32X80 directly; the ISO 15552 interface means FA, LB, and TC mounts transfer without machining. Size both ways by checking neighbour bores, but remember the double-rod geometry yields equal force in both directions (345 N at 0.5 MPa). A double rod is right when you need anti-rotation stability or want to drive two tools from one piston. Because this SKU has no -S magnet, sensor tracking is impossible. For this 80 mm stroke side-load is minimal, but for any stroke >=300 mm verify your guide tolerances.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X80
- ✓ 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 SID32X80 FAQ
Yes, the SID32X80 is discontinued. The direct replacement is the SAID32X80. It shares the same ISO 15552 mounting interface, 32 mm bore, 80 mm stroke, G1/8 port, and equal both ways force, while adding an upgraded piston seal.
The G1/8 port bore delivers force equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. It operates at 0.15-1.0 MPa, runs 30-800 mm/s, and the air cushion only decelerates the load (it does not hold it without live air).
