This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X30CA, 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 SI80X30CA
The AirTAC SI80 Standard Air Cylinder SI80X30CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 30mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X30CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X30CA
The AirTAC SI80X30CA is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 30mm stroke. Delivering 2513 N push force at 0.5 MPa via a G3/8 port, its direct replacement is the SAI80X30CA, which shares the identical CA clevis mounting interface and dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot accept a sensor; legacy CS1-B/DS1-B switches only fit -S models.

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 SAI80X30CA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80X30CA Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping of heavy steel plates in machining fixtures using the 30mm stroke.
Transfer Diverters
Provides robust 80mm bore actuation to push heavy pallets onto secondary conveyor lines with CA clevis pivoting.
Pallet Stops
Acts as a heavy-duty end-stop for inbound pallets, absorbing kinetic energy using the adjustable 36mm air cushion.
Replacing the Airtac SI80 Standard Air Cylinder SI80X30CA with the SAI80X30CA
To replace the SI80X30CA, order the SAI80X30CA. Verify the ISO 15552 CA clevis mount, 80mm bore, 30mm stroke, G3/8 port (PT/G/NPT thread options), and rod-end M20x1.5 thread. This non-magnet version cannot hold a position sensor. If you need more force, the 100mm bore yields 3927 N push at 0.5 MPa; if less is acceptable, the 63mm bore provides 1559 N. The cushion only decelerates the load; it does not hold it. For load holding on air loss, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The SAIF variant integrates a 4M valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X30CA
- ✓ 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 SI80X30CA FAQ
Yes, the AirTAC SI80X30CA is discontinued. The direct replacement is the SAI80X30CA. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 30mm stroke, CA clevis mount, G3/8 port, and 2513 N output force.
The 80mm bore features a G3/8 port and delivers 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
