About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-75
Because the adjustment range equals the nominal stroke, operators can dial the effective travel anywhere within a 0-75 mm window. This allows precise end-position tuning at commissioning without swapping out the entire actuator or fabricating external stops.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. While the rear adjuster sets the travel limit, it functions strictly as a mechanical stop and does not hold the 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 SAIJ100AX75-75 Is Used
Product Changeover
Quickly modify the extend position within the 0-75 mm window to accommodate different package sizes on a packaging line without changing cylinders.
Machine Setup
Fine-tune the end-stop during initial commissioning to dial in exact positioning, preventing hard crashes and ensuring precise mechanical alignment.
Variable End Stops
Establish multiple adjustable retract distances in automated assembly equipment where the rear stroke limit frequently changes based on the tooling installed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-75 the Right Cylinder?
If an application needs less force, stepping down to an 80mm bore yields 3518N at 0.7 MPa, whereas larger loads up to 8590N at 0.7 MPa require moving to a 125mm bore.
For a direct ISO 15552 replacement match, confirm the 100mm bore, 75mm stroke, PT port thread, and the specific 75mm adjustment code. This model omits standard mounting hardware like FB, CA, CB, and CR, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since the stroke is under 300mm, external side-load guides are less critical, but the robust 25mm rod still handles standard operational stresses effectively.
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 SAIJ100AX75-75 FAQ
At 0.5 MPa, the push force is 3927N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective travel anywhere within a 0-75 mm window from the nominal stroke. It does not lock the load without live air; for load-holding, consider a SAIL or BSAI cylinder.
