About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-40
The AirTAC SAIJ160X180-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering heavy-duty thrust up to 18095N at 0.9 MPa. It features a robust 40mm diameter SUS304 stainless steel rod and PT tapered ports. By integrating an external adjusting screw, this model allows you to trim the effective travel back by up to 40mm, creating a precise 140-180mm usable stroke window without swapping out the entire actuator.
This fine-tuning capability is ideal for dialing in end positions during commissioning or adapting to new product sizes on the fly. The extruded aluminum barrel includes dual sensor grooves, and while this unit omits a magnet, the design supports AirTAC CMSE reed and DMSE electronic sensors when needed. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ160BX180-40 Is Used
Heavy-Duty Press Tuning
Dial in the exact 140-180mm end position during machine commissioning to accommodate varying material thicknesses without adding external stopper blocks.
Product Changeover Diverter
Quickly adjust the retract stroke by up to 40mm on a packaging line to handle different carton sizes on the fly, ensuring precise mechanical positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-40 the Right Cylinder?
Select this 160mm bore actuator when an application demands high pull force, rated at 9425N at 0.5 MPa, alongside variable end-stop positioning. If your setup requires less force, stepping down to a 125mm bore yields 5734N of pull force at 0.5 MPa, whereas moving up to a 200mm bore provides 15080N. Choose the SAIJ adjustable format over a fixed-stroke SAI cylinder when you need on-the-fly end-position tuning during product changeovers rather than relying on external mechanical stops.
Because the nominal stroke is 180mm, external guiding is recommended to manage side loads. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable profile exactly, specify the 160mm bore, 180mm stroke, 40mm adjustment, PT ports, SUS304 rod, and your required mounting bracket.

- ✓ 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 SAIJ160BX180-40 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the nominal 180mm stroke by up to 40mm, providing a usable travel window of 140-180mm. This allows precise end-position tuning at commissioning without changing the cylinder.
At 0.9 MPa operating pressure, the push force is 18095N and the pull force is 9425N.
