This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X190S, 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 SI80X190S
The AirTAC SI80 Standard Air Cylinder SI80X190S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X190S
The AirTAC SI80X190S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 190mm stroke. Delivering 2513 N push force at 0.5 MPa, it features a G3/8 port, M20x1.5 rod thread, and adjustable air cushions. The direct replacement is the SAI80X190S, retaining identical ISO 15552 mounting dimensions, output force, and accessories.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors.

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 SAI80X190S 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 SI80X190S Is Used
Pallet Diversion
Executes 190mm strokes to divert heavy pallets on packaging lines, relying on adjustable 36mm air cushions to decelerate the 80mm bore smoothly.
Material Lift Gates
Actuates industrial lift gates and heavy doors, where the G3/8 port and 30-800 mm/s speed range provide responsive pneumatic control.
Replacing the Airtac SI80 Standard Air Cylinder SI80X190S with the SAI80X190S
To replace the SI80X190S, order the SAI80X190S and confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), G3/8 port thread (PT/G/NPT), and the -S magnet. Sizing both ways: a 63mm bore yields 1559 N push @0.5 MPa, while a 100mm bore yields 3927 N. For this 190mm stroke, ensure guide alignment to prevent rod bending. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. The SAI family also offers the SAIF self-valve for bores up to 100mm.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X190S
- ✓ 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 SI80X190S FAQ
Yes, the SI80X190S is discontinued. The direct replacement is the SAI80X190S. It features the same ISO 15552 mounting interface, 80mm bore, 190mm stroke, G3/8 port, and output force, fitting existing fixtures perfectly.
The 80mm bore uses a G3/8 port. It delivers 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.
