This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX600, 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 SI100AX600
The AirTAC SI100 Standard Cylinder SI100AX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX600
The AirTAC SI100AX600 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 600mm stroke. Delivering 3927N push force at 0.5MPa via a G1/2 port, it is replaced by the SAI100AX600 direct equivalent sharing the same interface, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU uses an SUS420J2 stainless rod (A) and lacks a magnet, so it cannot take CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100AX600 Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy-gauge workpiece diverters on high-capacity conveyor lines requiring a 600mm reach.
Automated Warehousing
Actuates large vertical lift gates and heavy pusher mechanisms in automated storage and retrieval systems.
Large Assembly Press
Provides the 3927N push force at 0.5MPa needed to position heavy chassis components in automotive assembly cells.
Replacing the Airtac SI100 Standard Cylinder SI100AX600 with the SAI100AX600
To replace the SI100AX600, order the SAI100AX600. Confirm the ISO 15552 mounting interface, 100mm bore, 600mm stroke, G1/2 port (PT/G/NPT), and your specific mounting accessory. This non-magnet SKU cannot accept position sensors. For sizing, neighboring bores offer different forces: an 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. Because the 600mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX600
- ✓ 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 SI100AX600 FAQ
Yes, the SI100AX600 is discontinued. The direct replacement is the SAI100AX600. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 600mm stroke, force, G1/2 port, and mounting interface.
This double-acting cylinder has a G1/2 port. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa.
