This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X192SN, 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 SI80X192SN
The AirTAC SI80 Standard Air Cylinder SI80X192SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 192mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X192SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X192SN
The AirTAC SI80X192SN is a discontinued double-acting ISO 15552 profile cylinder with a 192 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. Because 192 mm is a non-standard stroke, expect a custom or extended lead time. The direct replacement is the SAI80X192SN, retaining the same bore, force, port and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. This -SN unit has an NBR seal (-20 to +70 C) and a 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 SAI80X192SN 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 SI80X192SN Is Used
Package Diversion
Drives heavy sorting gates on packaging lines where the 2513 N push force at 0.5 MPa easily redirects weighted totes.
Clamp Actuation
Secures large steel workpieces in machining fixtures, providing reliable holding against cutting forces.
Pallet Handling
Lifts and positions loaded pallets at transfer stations, safely managing vertical loads up to 128 kg.
Replacing the Airtac SI80 Standard Air Cylinder SI80X192SN with the SAI80X192SN
To replace this SI80X192SN, order the SAI80X192SN. It drops directly into existing ISO 15552 fixtures with identical bore, stroke, G3/8 port and mounting. Confirm your port thread (PT, G or NPT) and mounting accessory (like FA flange or TC trunnion). The -S magnet works with legacy CS1-B/DS1-B switches, while the SAI uses current AirTAC sensors. The -N NBR seal is standard.
For sizing both ways: if you need less force, the 63 mm bore offers 1559 N push at 0.5 MPa; if you need more, the 100 mm bore provides 3927 N. Because 192 mm is non-standard, verify lead times. For any stroke over 300 mm, use a guide to prevent rod bending and side-load wear. A plain cylinder drifts without live air; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X192SN
- ✓ 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 SI80X192SN FAQ
Yes, the SI80X192SN is discontinued. The direct replacement is the SAI80X192SN. It shares the same ISO 15552 mounting interface, 80 mm bore, 192 mm stroke, output force, G3/8 port and accessories, fitting existing fixtures perfectly.
This double-acting cylinder has a G3/8 air port. It generates 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.
