This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X580, 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 SI100 Standard Cylinder SI100X580
The AirTAC Airtac SI100 Standard Cylinder SI100X580 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 580mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X580, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X580
The AirTAC SI100X580 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 580mm stroke, delivering 3927N push force at 0.5MPa. AirTAC replaced it with the SAI100X580, a direct upgrade retaining the exact interface, port, and force.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor. Note the G1/2 port.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X580 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |

Where the Airtac SI100 Standard Cylinder SI100X580 Is Used
Pallet Diversion
Shifts heavy pallets laterally across high-throughput conveyor lines using robust 3927N push force at 0.5MPa.
Press Ejection
Ejects formed metal components from hydraulic presses, utilizing the 580mm stroke for deep-bed clearance.
Replacing the Airtac SI100 Standard Cylinder SI100X580 with the SAI100X580
To replace the SI100X580, order SAI100X580 and confirm the ISO 15552 mounting, G1/2 port, and M20x1.5 thread. This no-S SKU lacks a magnet and cannot accept a sensor. For sizing, a neighboring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. With a 580mm stroke, use external guides to prevent rod bending and side loads. The cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X580
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X580 FAQ
Yes, the SI100X580 is discontinued. The direct replacement is the SAI100X580, which shares the identical ISO 15552 mounting interface, 100mm bore, 580mm stroke, and G1/2 port for a seamless fixture swap.
It features a G1/2 port. Force output is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa.
