This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X30, 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 SI80X30
The AirTAC SI80 Standard Air Cylinder SI80X30 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 SAI80X30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X30
The AirTAC SI80X30 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 30 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X30, which matches the exact ISO 15552 mounting interface, output force, and dimensions.
This SKU lacks a magnet and cannot accept a sensor. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure.

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 SAI80X30 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 SI80X30 Is Used
Short-Stroke Clamping
Ideal for holding heavy castings during machining, using the 2513 N push force to secure parts firmly within a compact 30 mm travel.
Pallet Diverter
Provides robust actuation for diverting heavy goods pallets on a packaging line, benefiting from the G3/8 port for rapid response.
Bin Gate Actuation
Handles the quick opening and closing of bulk material bin gates where high initial thrust is needed over a brief 30 mm displacement.
Replacing the Airtac SI80 Standard Air Cylinder SI80X30 with the SAI80X30
To replace the SI80X30, order the SAI80X30. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/8 port thread (PT/G/NPT), and the M20x1.5 rod end. Since this non-magnetic SKU cannot fit a sensor, order an SAI80X30S if position detection is required. If sizing up or down, note the 63 mm bore yields 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N. A plain cylinder drifts on air loss; for load holding, use the SAIL or BSAI lock variants, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X30
- ✓ 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 SI80X30 FAQ
Yes, the AirTAC SI80X30 is discontinued. The direct replacement is the SAI80X30. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 30 mm stroke, 2513 N force, G3/8 port, and mounting interface.
This double-acting cylinder uses a G3/8 port and features a 25 mm rod with M20x1.5 thread. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa.
