This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X110H, 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 SI80X110H
The AirTAC SI80 Standard Air Cylinder SI80X110H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 110mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X110H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X110H
The AirTAC SI80X110H is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 110mm stroke, and a Viton H high-temperature seal (0 to 150 C). Generating 2513 N push and 2268 N pull at 0.5 MPa, it features a Ø25mm rod, M20x1.5 thread, and a G3/8 air port. Because this SKU lacks a magnet (-S), it cannot accept a position sensor.
This SI unit is replaced by the SAI80X110H. The SAI is a direct upgrade retaining the exact ISO 15552 mounting interface, bore, force, and port size, but adds an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X110H carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI80X110H 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 SI80X110H Is Used
High-Temperature Forming
Drives press tooling in hot zones up to 150 C using the Viton H seal, providing 2513 N of thrust at 0.5 MPa.
Heavy Part Diversion
Pushes dense metal or composite workpieces off a main belt, safely handling a 1508 N working load.
Pallet Stop Gate
Acts as a robust 80mm bore stopper on outbound palletizers, offering 128 kg vertical lift capacity.
Replacing the Airtac SI80 Standard Air Cylinder SI80X110H with the SAI80X110H
To replace the discontinued SI80X110H, order the SAI80X110H. Confirm the ISO 15552 mounting interface, 110mm stroke, G3/8 port, and your specific mounting accessory (LB, FA, TC, etc.). This non-magnetic SKU cannot support switches; if sensing is needed, select an SAI80X110HS and use current AirTAC switches instead of the legacy CS1-B/DS1-B. Sizing both ways: a 63mm bore yields 1559 N push at 0.5 MPa, while a 100mm bore yields 3927 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use the SAIL or BSAI lock variants, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X110H
- ✓ 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 SI80X110H FAQ
Yes, the SI80X110H is discontinued. The direct replacement is the SAI80X110H. It shares the identical ISO 15552 mounting interface, 80mm bore, 110mm stroke, G3/8 port, and force ratings, but features an upgraded two Y-shaped element piston seal for longer life.
The G3/8 port bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 36mm adjustable air cushion.
