This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X60H, 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 SI80X60H
The AirTAC SI80 Standard Air Cylinder SI80X60H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X60H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X60H
The AirTAC SI80X60H is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. Built for high-temperature duty, its Viton H seals handle 0 to 150 C. It delivers 2513 N push force at 0.5 MPa through a 25 mm rod and G3/8 port. The direct replacement is the SAI80X60H, which retains identical ISO 15552 mounting dimensions, bore, stroke, force and port size.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet, so it cannot accept position switches.

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 SAI80X60H 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 SI80X60H Is Used
Hot Stamp Presses
Drives tooling in high-temperature stamping cells where ambient heat requires Viton H seals rated for 150 C.
Diverting Gates
Short 60 mm stroke rapidly shifts flow gates at 30-800 mm/s without exceeding spatial limits.
Replacing the Airtac SI80 Standard Air Cylinder SI80X60H with the SAI80X60H
To replace the SI80X60H, order the SAI80X60H. Confirm the ISO 15552 mounting interface, 80 mm bore, 60 mm stroke, G3/8 port, and your Viton H high-temperature seal requirement. If you need position sensing, switch to an SAI80X60HS magnet model, as this legacy unit cannot take a sensor. For sizing alternatives, dropping to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. Remember that a standard cylinder drifts without live air; for load holding on valve center or air loss, use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. The SAI family also offers the SAIF variant with a built-in 4M valve for bores up to 100 mm.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X60H
- ✓ 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 SI80X60H FAQ
Yes, the SI80X60H is discontinued. The direct replacement is the SAI80X60H. It features the same ISO 15552 mounting interface, 80 mm bore, 60 mm stroke, G3/8 port, and Viton H high-temperature seals, fitting directly into existing fixtures.
The G3/8 port feeds a 25 mm rod to deliver 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
