This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X150TCN, 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 SI80X150TCN
The AirTAC SI80 Standard Air Cylinder SI80X150TCN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X150TCN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X150TCN
The AirTAC SI80X150TCN is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 150mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port. The direct replacement is the SAI80X150TCN, matching the exact TC trunnion mount, M20x1.5 rod thread, and output force.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. This specific SKU lacks the -S magnet, so it cannot accept CS1-B/DS1-B sensors. For high heat, choose the Viton H seal option (0-150C).

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 SAI80X150TCN 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 SI80X150TCN Is Used
Mid-Tonnage Pressing
Applies the 3518N push at 0.7MPa for seating bearings or light stamping tasks within automated cells.
Pallet Diverting
Uses the TC trunnion mount to handle side loads while pushing heavy pallets off a main transfer line.
Replacing the Airtac SI80 Standard Air Cylinder SI80X150TCN with the SAI80X150TCN
To replace the SI80X150TCN, order the SAI80X150TCN. It is dimensionally interchangeable per ISO 15552, keeping the 80mm bore, 150mm stroke, G3/8 port, and TC trunnion mounting. When sizing, verify force both ways: dropping to a 63mm bore yields 1559N push, while stepping up to 100mm provides 3927N at 0.5MPa. A plain cylinder drifts on air loss; the 36mm cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. If you need integrated valves, the SAIF variant fits 32-100mm bores.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X150TCN
- ✓ 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 SI80X150TCN FAQ
