About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-40S
The AirTAC SAIJ100X700-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 700 mm nominal stroke and a 40 mm adjustment range, you can dial back the effective travel to anywhere within a 660-700 mm window during commissioning without adding external stops.
This unit includes a magnet (-S) for electronic DMSE or reed CMSE sensors, fitting neatly into the dual-side sensor grooves of its extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not lock the load. For true position holding without live air pressure, AirTAC SAIL or BSAI cylinders are required. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX700-40S Is Used
Product Changeover
Rapidly shift the end-stop within the 660-700 mm window to accommodate varying product lengths on a packaging line without swapping hardware.
Machine Setup
Fine-tune the final retract position during commissioning to align tooling perfectly, using the 40 mm adjuster to avoid machining custom spacers.
Variable End Stops
Establish precise mechanical travel limits on automated assembly equipment where multiple stroke endpoints are required.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-40S the Right Cylinder?
Choose the adjustable SAIJ over a fixed SAI when a machine requires variable end-stops for rapid product changeover. To match this ISO 15552 footprint, specify the 100 mm bore, 700 mm stroke, 40 mm adjustment, PT G1/2 port, and the -S magnet. Because the 700 mm stroke is long and the 25 mm rod is unsupported, an external guide is recommended to prevent rod bending under high side loads.
Quick checklist
- ✓ 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 SAIJ100AX700-40S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 40 mm, creating a 660-700 mm usable travel window. It only sets the end position and does not hold the load without live air pressure.
