This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X210TC, 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 SI80X210TC
The AirTAC SI80 Standard Air Cylinder SI80X210TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 210mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X210TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X210TC
The AirTAC SI80X210TC is a discontinued double-acting ISO 15552 profile cylinder with a 210 mm stroke. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the SAI80X210TC, retaining the exact bore, stroke, force, port, TC trunnion mount and ISO 15552 interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. This no-magnet SKU cannot take a sensor; legacy CS1-B/DS1-B switches require the -S version.

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 SAI80X210TC 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 SI80X210TC Is Used
Press Ejection
Provides the 2513 N push at 0.5 MPa required to eject formed metal parts from heavy stamping dies.
Pallet Diverting
Uses the 210 mm stroke to push heavy pallets smoothly across transfer lines via the TC trunnion mount.
Replacing the Airtac SI80 Standard Air Cylinder SI80X210TC with the SAI80X210TC
To replace the SI80X210TC, order the SAI80X210TC with the TC trunnion mount, verifying your ISO 15552 interface dimensions, 80 mm bore, 210 mm stroke, G3/8 port (PT/G/NPT thread) and M20x1.5 rod thread. This non-magnetic SKU cannot accept a sensor; if position detection is needed, select an SAI80X210S equivalent and use current AirTAC switches. Sizing both ways: the 80 mm bore yields 2513 N push at 0.5 MPa (4523 N at 0.9 MPa), while a neighbouring 100 mm bore provides 3927 N at 0.5 MPa. A plain cylinder drifts on air loss since cushions only decelerate; for load holding use an external pilot check valve or the SAIL/BSAI lock variants. At 210 mm stroke, guide external rods to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X210TC
- ✓ 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 SI80X210TC FAQ
Yes, the SI80X210TC is discontinued. The direct replacement is the SAI80X210TC. It shares the same ISO 15552 mounting interface, 80 mm bore, 210 mm stroke, G3/8 port, output force and TC trunnion mount, fitting existing fixtures perfectly.
The 80 mm bore uses a G3/8 port. Force ratings are 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 max of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
