This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X80CA, 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 SI80 Standard Air Cylinder SI80X80CA
The AirTAC Airtac SI80 Standard Air Cylinder SI80X80CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X80CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X80CA
The AirTAC SI80X80CA is a discontinued double-acting ISO 15552 profile cylinder. It delivers 2513 N push and 2268 N pull at 0.5 MPa via a 25mm rod and G3/8 port. The direct replacement is the SAI80X80CA, which matches the 80mm bore, 80mm stroke, CA clevis mount and output force exactly.
This SAI upgrade introduces a two-piece Y-shaped piston seal for low start-up pressure and extended life. Note this non-magnet SKU cannot hold position without live air; the cushion only decelerates.

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

Where the Airtac SI80 Standard Air Cylinder SI80X80CA Is Used
Press Ejection
Provides 2513 N of push force at 0.5 MPa to reliably eject stamped parts from a press bed using the CA clevis mount.
Package Diverting
Drives a heavy-duty diverter arm on a packaging line, utilizing the 80mm stroke to route cartons at speeds up to 800 mm/s.
Replacing the Airtac SI80 Standard Air Cylinder SI80X80CA with the SAI80X80CA
To replace the SI80X80CA, order the SAI80X80CA and confirm the ISO 15552 mounting interface, CA clevis, 80mm stroke and G3/8 port. Because this specific SKU lacks the -S magnet, it cannot accept CS1-B or DS1-B sensors; order a magnet-equipped variant if position sensing is needed. Sizing down, a 63mm bore yields 1559 N push at 0.5 MPa; sizing up, a 100mm bore yields 3927 N. For load holding on air loss, add an external pilot check valve or rod lock, or specify the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X80CA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X80CA FAQ
Yes, the SI80X80CA is discontinued. The direct replacement is the SAI80X80CA. It shares the identical ISO 15552 mounting interface, 80mm bore, 80mm stroke, G3/8 port and CA clevis, fitting existing fixtures perfectly.
It features a G3/8 port and 25mm rod. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
