This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX95S, 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 SI80BX95S
The AirTAC SI80 Standard Air Cylinder SI80BX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX95S
The AirTAC SI80BX95S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N push force at 0.5 MPa. It features a SUS304 stainless piston rod (-B), a built-in magnet (-S) for CS1-B/DS1-B sensors, and a G3/8 air port. AirTAC replaced this legacy unit with the SAI80BX95S.
The SAI80BX95S is a direct replacement retaining the exact ISO 15552 mounting interface, 95 mm stroke, and force. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. Note the cushion only decelerates; use SAIL or BSAI variants for load holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80BX95S 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 SAI80BX95S 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 SI80BX95S Is Used
Stainless Rod Actuation
Drives clamping arms in washdown environments using the SUS304 rod, providing 2513 N push force at 0.5 MPa.
Package Diverting
Pushes heavy cartons off a main belt with a 95 mm stroke, safely handling a 1508 N working load.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX95S with the SAI80BX95S
To replace the SI80BX95S, order the SAI80BX95S. Confirm the ISO 15552 mounting fixture, 80 mm bore, 95 mm stroke, G3/8 port, and the -S magnet for current AirTAC switches. The -B rod is SUS304 stainless steel. Sizing both ways: this bore gives 2513 N push at 0.5 MPa; if less force is needed, a 63 mm bore offers 1559 N. If more is needed, a 100 mm bore gives 3927 N. A plain cylinder drifts on air loss—use the SAIL lock or BSAI clamp-lock variant for held loads. The SAIF variant integrates a 4M valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX95S
- ✓ 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 SI80BX95S FAQ
Yes, the SI80BX95S is discontinued. The direct replacement is the SAI80BX95S. It shares the same ISO 15552 mounting interface, 80 mm bore, 95 mm stroke, force, and G3/8 port, fitting existing fixtures directly.
The G3/8 port delivers a push of 2513 N and pull of 2268 N at 0.5 MPa. At 0.7 MPa push is 3518 N, and 4523 N at 0.9 MPa. The theoretical max force is 513 kgf at 1.0 MPa.
