About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-75S
The AirTAC SAIJ100X400-75-S is a double-acting ISO 15552 profile cylinder featuring a double rod made of SUS420J2 stainless steel and a built-in magnet for position sensing. A rear adjusting screw allows you to shorten the effective stroke by up to 75 mm, creating a usable travel window of 325 to 400 mm for precise end-position tuning. It delivers substantial thrust, pushing 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa, while pulling 3681 N at 0.5 MPa.
Equipped with a PT G1/2 port and variable air cushions at both ends, this extruded aluminum barrel design integrates sensor grooves on both sides. These grooves accept AirTAC CMSE reed switches and DMSE solid-state electronic sensors, giving you flexible detection options. The rear stopper acts purely as a travel end deceleration device, so it will not hold a load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-75S Is Used
Variable End-Stop Machining
Dial in the retract distance from 325 to 400 mm during commissioning to accommodate different part lengths without changing the cylinder setup.
Product Changeover Diverter
Quickly adjust the stroke by up to 75 mm when switching the conveyor line to handle a new package size, ensuring precise routing.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-75S the Right Cylinder?
Choose this 100 mm bore when the smaller 80 mm version (which provides 2268 N pull at 0.5 MPa) lacks the necessary force for your heavy loads. An adjustable stroke is ideal for machine setup and product changeover, letting you fine-tune the retract distance on the fly without swapping cylinders or adding external stops. If your application requires true load-holding without live air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock cylinder instead, as the SAIJ adjuster is only a stop. Because the 400 mm stroke is substantial and the rod is relatively unsupported over that length, adding an external guide is recommended to prevent excessive side-loading. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 400 mm stroke, 75 mm adjustment, PT G1/2 port, SUS420J2 rod, and the -S magnet.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-75S FAQ
A screw at the rear of the cylinder acts as a mechanical stop, allowing you to trim the nominal 400 mm stroke back by up to 75 mm. This creates a usable travel window of 325 to 400 mm for precise end-position tuning.
