This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1000SLB, 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 SI80X1000SLB
The AirTAC SI80 Standard Air Cylinder SI80X1000SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1000SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1000SLB
The AirTAC SI80X1000SLB is a discontinued double-acting ISO 15552 profile cylinder with a 1000 mm stroke, delivering 2513 N push force at 0.5 MPa. It features a built-in piston magnet for CS1-B/DS1-B switches and an LB foot mount. Because this SI unit is end-of-life, order the direct replacement: SAI80X1000SLB.
The SAI80X1000SLB matches the original 80 mm bore, stroke, G3/8 port and ISO 15552 mounting interface. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. For load holding, note that a plain cylinder drifts without air; use an external rod lock or the SAIL/BSAI variants.

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 SAI80X1000SLB 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 SI80X1000SLB Is Used
Long-Stroke Material Transfer
Drives heavy pallets along extended conveyor sections using the 1000 mm stroke, relying on external guides to prevent rod deflection during transit.
Large Press Ejection
Pushes finished components out of wide machinery beds, utilizing the 80 mm bore to deliver 2513 N of ejection force at 0.5 MPa.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1000SLB with the SAI80X1000SLB
To replace the SI80X1000SLB, order SAI80X1000SLB. Verify the ISO 15552 interface, 80 mm bore, 1000 mm stroke, G3/8 port, LB foot mount, and the -S magnet for current AirTAC switches. The SAI direct provides 513 kgf max force. If sizing down, a 63 mm bore yields 1559 N push at 0.5 MPa; sizing up to 100 mm provides 3927 N. For this 1000 mm stroke, use an external guide to prevent rod bending and side loads. A plain cylinder does not hold load without live air—the cushion only decelerates—so add a pilot check valve or explore the SAIL lock or SAIF self-valve variants for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1000SLB
- ✓ 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 SI80X1000SLB FAQ
Yes, the SI80X1000SLB is discontinued. The direct replacement is the SAI80X1000SLB. It offers the same ISO 15552 mounting interface, 80 mm bore, 1000 mm stroke, output force, G3/8 port and LB foot mount, fitting directly into existing fixtures.
The G3/8 port feeds a 25 mm rod. At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
