This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X130TC, 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 SI80X130TC
The AirTAC SI80 Standard Air Cylinder SI80X130TC 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 SAI80X130TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X130TC
The AirTAC SI80X130TC is a discontinued double-acting ISO 15552 profile cylinder with a 130 mm stroke and TC trunnion mount. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X130TC, matching the bore, stroke, force, port and ISO 15552 mounting interface exactly.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. For load holding, note the air cushion only decelerates; use a pilot check valve or SAIL lock variant.

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 SAI80X130TC 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 SI80X130TC Is Used
Pallet Diverting
Uses the TC trunnion mount to pivot and deflect heavy pallets along a packaging line, utilizing the 2513 N push force at 0.5 MPa.
Press Ejection
Ejects formed metal components from a press bed, relying on the 36 mm adjustable air cushions to decelerate the 25 mm rod at stroke ends.
Replacing the Airtac SI80 Standard Air Cylinder SI80X130TC with the SAI80X130TC
To replace the SI80X130TC, order the SAI80X130TC. Confirm the ISO 15552 TC trunnion interface, 80 mm bore, 130 mm stroke, G3/8 port (PT/G/NPT thread options) and M20x1.5 rod thread. This non-magnetic SKU cannot take a switch; if sensing is needed, select an SAI model with the S magnet suffix for current AirTAC switches. At 0.5 MPa it yields 2513 N push; neighbouring bores are 63 mm (1559 N) and 100 mm (3927 N). For vertical loads, a plain cylinder drifts without air—the cushion decelerates but does not lock—so add a pilot check valve, external rod lock, or choose the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X130TC
- ✓ 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 SI80X130TC FAQ
Yes, the SI80X130TC is discontinued. The direct replacement is the SAI80X130TC. It shares the identical ISO 15552 TC mounting interface, 80 mm bore, 130 mm stroke, G3/8 port and output force, fitting existing fixtures perfectly while upgrading the piston seal.
It has a G3/8 air port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa.
