This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X130S, 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 SI80X130S
The AirTAC SI80 Standard Air Cylinder SI80X130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X130S
The AirTAC SI80X130S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 130mm stroke. It delivers 2513N push force at 0.5MPa via a G3/8 port. The direct replacement is the SAI80X130S, matching the bore, stroke, force, port, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, while SAI uses current AirTAC switches.

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 SAI80X130S 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 SI80X130S Is Used
Clamp Actuation
Provides 2513N push force at 0.5MPa for securing heavy workpieces during CNC machining operations.
Package Diversion
Drives 130mm stroke diverters to route moderate-weight goods across material handling lines.
Pallet Lift Stops
Acts as a robust pneumatic stop mechanism for palletized loads entering storage bays.
Replacing the Airtac SI80 Standard Air Cylinder SI80X130S with the SAI80X130S
To replace the SI80X130S, order the SAI80X130S. Confirm the ISO 15552 mounting interface, 80mm bore, 130mm stroke, G3/8 port (PT/G/NPT), and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors. Sizing both ways: neighbor bores are 63mm (1559N push @0.5MPa) and 100mm (3927N push @0.5MPa). A plain cylinder drifts on air loss; for load holding use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. The SAI family also offers the SAIF self-valve variant. At 130mm stroke, side-load is minimal, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X130S
- ✓ 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 SI80X130S FAQ
Yes, the SI80X130S is discontinued. The direct replacement is the SAI80X130S. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 130mm stroke, output force, G3/8 port, and mounting interface.
This 80mm bore cylinder features a G3/8 port and delivers 2513N push / 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa.
