This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X100SLB, 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 SI80X100SLB
The AirTAC SI80 Standard Air Cylinder SI80X100SLB 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 SAI80X100SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X100SLB
The AirTAC SI80X100SLB is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore, 100mm stroke, LB foot mount, and a piston magnet. Delivering 2513N push force at 0.5MPa, it is replaced by the SAI80X100SLB. This direct upgrade retains the exact G3/8 port, M20x1.5 thread, and 36mm cushions. The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure, and adds SAIL, SAIF, and BSAI lock variants.
The -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI uses current switches. A plain cylinder drifts on air loss, so use an external rod lock or SAIL variant for load holding.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X100SLB Is Used
Press Clamping
Secures heavy workpieces during machining operations, utilizing the 2513N push force at 0.5MPa to prevent movement under cutting loads.
Pallet Diverter
Actuates routing gates on high-speed packaging lines, with the LB foot mount providing stability against lateral impacts during diversion.
Replacing the Airtac SI80 Standard Air Cylinder SI80X100SLB with the SAI80X100SLB
To replace the SI80X100SLB, order the SAI80X100SLB. It drops directly into existing fixtures via the ISO 15552 mounting interface, matching the 80mm bore, 100mm stroke, LB foot mount, G3/8 port, and piston magnet. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore yields 3927N. Note that a plain cylinder does not hold load without live air, as cushions only decelerate. For secure holding, consider the SAIL lock or BSAI clamp-lock variants, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X100SLB
- ✓ 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 SI80X100SLB FAQ
Yes, the SI80X100SLB is discontinued. The direct replacement is the SAI80X100SLB. It shares the identical ISO 15552 mounting interface, 80mm bore, 100mm stroke, G3/8 port, and LB foot mount, fitting existing fixtures perfectly while upgrading the seal design.
The 80mm bore features a G3/8 air port and M20x1.5 rod thread. It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa.
