This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX1300S, 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 SI80BX1300S
The AirTAC SI80 Standard Air Cylinder SI80BX1300S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1300mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX1300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX1300S
The AirTAC SI80BX1300S is a discontinued double-acting ISO 15552 profile cylinder with a 1300 mm stroke, SUS304 stainless piston rod, and a built-in magnet. Generating 2513 N push force at 0.5 MPa, it is replaced by the SAI80BX1300S direct upgrade. This successor matches the 80 mm bore, stroke, G3/8 port, and mounting interface exactly, while introducing an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
The original SI utilized CS1-B/DS1-B legacy sensors, whereas the current SAI family uses modern AirTAC switches. Furthermore, the SAI line expands functionality with SAIL, SAIF, and BSAI lock or integrated-valve variants that the legacy SI series lacked.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80BX1300S Is Used
High-Reach Vertical Lifting
Elevates goods up to 128 kg in storage retrieval systems, relying on the SUS304 stainless rod to resist moisture and corrosion in humid warehouse environments.
Large Fixture Actuation
Actuates oversized clamping fixtures on automated assembly lines, dropping directly into existing ISO 15552 mounts when upgraded to the SAI80BX1300S.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX1300S with the SAI80BX1300S
To replace the discontinued SI80BX1300S, order the SAI80BX1300S, ensuring a direct fit per the ISO 15552 mounting interface. Confirm the 80 mm bore, 1300 mm stroke, G3/8 port, and your specific mounting accessory (such as FA flange or TC trunnion). The S suffix indicates a piston magnet, so specify current AirTAC switches instead of the legacy CS1-B/DS1-B set. The B suffix denotes the SUS304 stainless rod for corrosion resistance.
When sizing, consider neighboring bores: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Note that a plain cylinder does not hold load on air loss; the cushion only decelerates near stroke end. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Because 1300 mm exceeds typical lengths, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX1300S
- ✓ 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 SI80BX1300S FAQ
Yes, the SI80BX1300S is discontinued. The direct replacement is the SAI80BX1300S. It shares the identical ISO 15552 mounting interface, 80 mm bore, 1300 mm stroke, G3/8 port, and output force, fitting existing fixtures perfectly while upgrading the piston seal.
The G3/8 port bore delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa the push force is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
