About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-40S
It features a SUS304 stainless steel rod and a PT tapered port. By turning the rear screw, you can trim the effective travel, creating a precise 100-140 mm usable window for your application without adding external stops.
This adjustable-stroke design allows for fine end-position tuning during commissioning or product changeovers. The cylinder includes a magnet for CMSE and DMSE sensors, utilizing the extruded aluminum barrel with sensor grooves on both sides. Remember that the rear adjuster acts as a travel stop, not a lock; it cannot hold a load without continuous live air pressure.

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 SAIJ160BX140-40S Is Used
Heavy Press Tuning
Dial in the exact 100-140 mm end position during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper on a packaging line to handle different product sizes, using the 40 mm trim range to adapt the stroke on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-40S the Right Cylinder?
Choose the SAIJ adjustable version over a fixed SAI when you need to dial in the exact 100-140 mm travel window on the fly. For load-holding without live air pressure, you must integrate an external rod lock or look into AirTAC SAIL or BSAI models. To replace an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 40 mm adjustment, PT G3/4 port, and the -S magnet requirement.
Although the stroke is 140 mm, the substantial 40 mm rod diameter and M36x2 thread handle significant side loads well. For any application extending to 300 mm or more, you should add an external guide to prevent premature wear.
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 SAIJ160BX140-40S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 140 mm stroke by up to 40 mm, providing a usable travel window of 100-140 mm. It only sets the end position and does not lock the load without live air.
