This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X100SCA, 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 SI80X100SCA
The AirTAC SI80 Standard Air Cylinder SI80X100SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X100SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X100SCA
The AirTAC SI80X100SCA is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X100SCA, matching the bore, stroke, force, port, and CA clevis mounting for immediate fixture compatibility.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S code means a magnet for CS1-B/DS1-B switches.

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 SAI80X100SCA 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 SI80X100SCA Is Used
Press Clamping
Secures heavy steel workpieces in machining fixtures, utilizing the 2513 N push force at 0.5 MPa to prevent shifting during milling.
Pallet Diverter
Actuates a routing gate on a 100 mm stroke to redirect heavy pallets between parallel packaging lines without cycle delay.
Replacing the Airtac SI80 Standard Air Cylinder SI80X100SCA with the SAI80X100SCA
To replace the SI80X100SCA, order the SAI80X100SCA. Verify the ISO 15552 CA clevis mounting, 80 mm bore, 100 mm stroke, G3/8 port, and the -S magnet. If you need more force, the neighboring 100 mm bore offers 3927 N push at 0.5 MPa; if less is required, the 63 mm bore provides 1559 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. Rod material options include carbon steel, SUS420J2, or SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X100SCA
- ✓ 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 SI80X100SCA FAQ
Yes, the SI80X100SCA is discontinued. The direct replacement is the SAI80X100SCA. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 100 mm stroke, CA clevis mount, G3/8 port, and output force.
The G3/8 port feeds a 25 mm rod. Forces 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 513 kgf maximum at 1.0 MPa. Speed is 30-800 mm/s.
