This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX110S, 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 SI80BX110S
The AirTAC SI80 Standard Air Cylinder SI80BX110S 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 SAI80BX110S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX110S
The AirTAC SI80BX110S is a discontinued double-acting ISO 15552 profile cylinder featuring an 80mm bore, 110mm stroke, and a SUS304 stainless piston rod. Delivering 2513 N push and 2268 N pull at 0.5 MPa, it is replaced by the SAI80BX110S. This direct upgrade matches the G3/8 port, M20x1.5 thread, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure and long life. The -S magnet works with legacy CS1-B/DS1-B switches. Note that air cushions only decelerate; use a SAIL lock or external check valve to hold loads.

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 SAI80BX110S 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 SI80BX110S Is Used
Stainless Rod Clamping
Uses the SUS304 rod for washdown resistance while providing 2513 N of clamping force at 0.5 MPa.
Package Diverting
110mm stroke pushes heavy cartons off a main belt, with the -S magnet triggering CS1-B sensors for position confirmation.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX110S with the SAI80BX110S
To replace the SI80BX110S, order the SAI80BX110S. Verify the ISO 15552 mounting interface, 80mm bore, 110mm stroke, G3/8 port, and -S magnet. The -B code specifies the SUS304 rod. Sizing both ways: a 63mm bore yields 1559 N [email protected], while a 100mm bore yields 3927 N. For load holding, standard cylinders drift on air loss; use the SAIL lock variant or a pilot check valve. The SAI family also adds SAIF valve and BSAI clamp-lock options. At 110mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX110S
- ✓ 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 SI80BX110S FAQ
Yes, the SI80BX110S is discontinued. The direct replacement is the SAI80BX110S. It shares the same ISO 15552 mounting interface, 80mm bore, 110mm stroke, output force, G3/8 port, and SUS304 rod, fitting existing fixtures perfectly.
It has a G3/8 air port. 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 max of 513 kgf at 1.0 MPa.
