This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX10SH, 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 SI80BX10SH
The AirTAC SI80 Standard Air Cylinder SI80BX10SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 10mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX10SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX10SH
The AirTAC SI80BX10SH is a discontinued double-acting ISO 15552 profile cylinder with a 10 mm stroke and 80 mm bore. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80BX10SH, matching the exact ISO 15552 mounting interface, stroke, force, and porting for seamless fixture integration.
This specific unit features a SUS304 stainless steel rod (-B), a high-temp Viton H seal (0-150 C), and a piston magnet (-S) for legacy CS1-B/DS1-B sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure.

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 SI80BX10SH Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping of heavy steel plates in machining fixtures, utilising the 10 mm stroke and SUS304 rod for corrosion resistance.
Hot-Environment Pressing
Suitable for short pressing operations in elevated temperatures up to 150 C, leveraging the Viton H high-temp seals and robust 80 mm bore thrust.
Ejector Mechanisms
Provides reliable 2268 N pull force at 0.5 MPa to eject dense molded parts from heated tooling, where the stainless rod prevents contamination.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX10SH with the SAI80BX10SH
To replace the SI80BX10SH, order the SAI80BX10SH. Confirm the ISO 15552 mounting interface, the 80 mm bore, the 10 mm stroke, the G3/8 port, and the -S magnet for current AirTAC switches. Retain the -B SUS304 rod and -H Viton seal options. If you need more force, the neighbouring 100 mm bore offers 3927 N push at 0.5 MPa; if less is acceptable, the 63 mm bore provides 1559 N. Remember that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX10SH
- ✓ 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 SI80BX10SH FAQ
Yes, the SI80BX10SH is discontinued. The direct replacement is the SAI80BX10SH. It is a true ISO 15552 profile cylinder that matches the 80 mm bore, 10 mm stroke, 2513 N force, G3/8 port, and mounting interface, fitting existing fixtures perfectly.
The G3/8 port feeds a 25 mm rod. At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
