This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX220H, 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 SI80BX220H
The AirTAC SI80 Standard Air Cylinder SI80BX220H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 220mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX220H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX220H
The AirTAC SI80BX220H is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 220mm stroke, Viton H high-temperature seals (0-150 C), and a SUS304 stainless steel rod. Delivering 2513 N push force at 0.5 MPa via a G3/8 port, its direct replacement is the SAI80BX220H. Because this SKU lacks a magnet (-S), it cannot accept position sensors.
The SAI80BX220H retains the same ISO 15552 mounting interface, bore, stroke, force, and port, fitting existing fixtures perfectly. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the legacy SI line.

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 SAI80BX220H 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 SI80BX220H Is Used
High-Temp Actuation
Drives heavy clamps and actuators near ovens or heat sources where the Viton H seal and SUS304 stainless rod endure 0-150 C environments without degrading.
Pallet Diversion
Pushes heavy loaded pallets off a main conveyor line using the 80mm bore's 513 kgf maximum theoretical output, ensuring positive lateral transfer.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX220H with the SAI80BX220H
To replace the SI80BX220H, order the SAI80BX220H. Confirm the ISO 15552 mounting interface, 80mm bore, 220mm stroke, G3/8 port, and your specific mounting accessory (LB, FA, TC, etc.). This unit uses a SUS304 stainless rod and Viton H seals for high-temperature environments (0-150 C). Since it lacks the -S magnet, it cannot support CS1-B/DS1-B sensors; order a magnet-equipped SAI if position detection is needed. Sizing both ways: an 80mm bore yields 2513 N push at 0.5 MPa, while a neighbouring 100mm bore offers 3927 N. Note that a plain cylinder drifts without live air; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 220mm stroke, side-load and rod-bending risks are minimal, but ensure proper guide alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX220H
- ✓ 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 SI80BX220H FAQ
Yes, the AirTAC SI80BX220H is discontinued. The direct replacement is the SAI80BX220H. It is dimensionally interchangeable per ISO 15552, matching the 80mm bore, 220mm stroke, 2513 N force, G3/8 port, and mounting interface, so it fits existing fixtures directly.
The bore is 80mm with a G3/8 air port. The force ratings are: 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 force of 513 kgf at 1.0 MPa. It operates at 30-800 mm/s.
