This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX1300SH, 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 SI80BX1300SH
The AirTAC SI80 Standard Air Cylinder SI80BX1300SH 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 SAI80BX1300SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX1300SH
The AirTAC SI80BX1300SH is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 1300 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80BX1300SH, matching the exact bore, stroke, force, port, and ISO 15552 mounting interface for seamless fixture integration. This configuration features a SUS304 stainless rod (-B), a piston magnet (-S), and Viton H seals for 0-150 C high-temperature environments.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The original SI -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family utilizes current AirTAC switches and adds SAIL, SAIF, and BSAI lock variants absent in the SI line.

Where the Airtac SI80 Standard Air Cylinder SI80BX1300SH Is Used
High-Temp Material Press
Leverages the 2513 N push force at 0.5 MPa and Viton H seals to actuate a heated forming press up to 150 C, with the SUS304 rod resisting corrosion.
Long-Stroke Transfer Arm
Utilizes the 1300 mm stroke to push heavy workpieces between conveyor stations, requiring external guides to prevent rod bending over the extended length.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX1300SH with the SAI80BX1300SH
To replace the SI80BX1300SH, order the SAI80BX1300SH. Confirm the ISO 15552 mounting interface, 80 mm bore, 1300 mm stroke, G3/8 port, and your specific mounting accessory (LB, FA, TC, etc.). The -S magnet enables position sensing (legacy CS1-B/DS1-B; SAI uses current AirTAC switches), while the -B SUS304 rod and -H Viton seals must be specified. For sizing, a neighboring 63 mm bore yields 1559 N push at 0.5 MPa, whereas a 100 mm bore provides 3927 N. At 1300 mm, prevent rod bending by using an external guide to absorb side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX1300SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
