About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-75S
Its nominal 140mm stroke can be dialed back by up to 75mm, providing a usable travel window of 65-140mm for precise end-position tuning during commissioning. This made-to-order configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
The rear adjuster acts purely as a mechanical stop to set the retract position without needing external stops, but it does not hold the load without live air pressure. Operating at 30-500mm/s, this extruded aluminum barrel design omits the FB, CA, CB, and CR mounts found on some standard cylinders, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX140-75S Is Used
Heavy Press Fit Tuning
Dial in the exact 65-140mm insertion depth for heavy press fits during machine setup, ensuring precise alignment without replacing the entire actuator.
Variable Product Changeover
Quickly adjust the retract end-stop on a production line to accommodate different product sizes, using the 75mm trim window to handle format changes on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-75S the Right Cylinder?
Select this 160mm bore cylinder when an application requires heavy thrust up to 14074N at 0.7MPa combined with variable end stops for product changeover. If you need less force, stepping down to a 125mm bore yields 8590N at 0.7MPa, whereas moving up to a 200mm bore provides 21991N at 0.7MPa. The adjustable stroke is ideal for fine-tuning the retract position at setup without swapping the cylinder.
Because this SKU features a -S magnet, it directly supports AirTAC CMSE reed switches and DMSE electronic solid-state sensors. For any load-holding requirements without continuous live air pressure, note that the rear adjuster is not a lock; you should instead specify an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable cylinder, confirm the 160mm bore, 140mm stroke, 75mm adjustment, PT tapered port, and SUS304 rod material.
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 SAIJ160 Adjustable Cylinder SAIJ160BX140-75S FAQ
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 75mm. This creates a usable travel window of 65-140mm, letting you fine-tune the end position at commissioning without adding external stops.
At 0.7 MPa operating pressure, the push force is 14074N and the pull force is 9425N.
