This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX195S, 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 SI80BX195S
The AirTAC SI80 Standard Air Cylinder SI80BX195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 195mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX195S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX195S
The AirTAC SI80BX195S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 195mm stroke, and a SUS304 stainless steel rod. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the current-production SAI80BX195S, which maintains the exact same mounting interface, output force, and stroke.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL and BSAI lock variants absent in the 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 SAI80BX195S 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 SI80BX195S Is Used
Stainless Rod Clamping
Leverages the SUS304 rod for corrosion resistance while providing 2513 N of clamping force at 0.5 MPa for machined metal parts.
Pallet Stopper Gate
Acts as a robust pneumatic stop on roller conveyors, benefiting from the direct replacement SAI80BX195S ISO 15552 dimensions for legacy fixture compatibility.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX195S with the SAI80BX195S
To replace this SI80BX195S, order the SAI80BX195S. Confirm the ISO 15552 mounting interface, the G3/8 port, your PT/G/NPT thread standard, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). The SUS304 -B rod offers corrosion resistance versus standard carbon steel. If sizing alternatives, an adjacent 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; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants. At 195mm stroke, side-load risks are low, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX195S
- ✓ 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 SI80BX195S FAQ
Yes, the SI80BX195S is discontinued. The direct replacement is the SAI80BX195S. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 195mm stroke, G3/8 port, and mounting interface, but features an upgraded two Y-shaped piston seal.
The G3/8 port feeds a 25mm rod. At 0.5 MPa it pushes 2513 N and pulls 2268 N. Push force is 3518 N at 0.7 MPa, 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa.
