About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-100
The AirTAC SAIJ160X180-100 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 180 mm stroke that can be dialed back by up to 100 mm, yielding a highly flexible 80-180 mm usable travel window for precise end-position tuning during commissioning.
The external rear stopper allows you to trim the retract position without swapping the cylinder or adding external stops, while the robust 40 mm rod and M36x2 thread handle significant side loads. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU lacks the internal magnet for CMSE or DMSE switches.

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 SAIJ160BX180-100 Is Used
Product Changeovers
Dial in the 80-180 mm travel window instantly during packaging line format changes without replacing hardware.
Machine Setup
Fine-tune the retract end-position at commissioning to dial out mechanical clearances on heavy fixtures.
Variable End Stops
Adjust the rear stopper screw to accommodate multiple part sizes on the same heavy-duty press.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-100 the Right Cylinder?
If your setup needs less force, stepping down to a 125 mm bore yields 8590 N at the same pressure. The 100 mm adjustment range is ideal for product-size changeovers on a line, providing a variable end-stop that fixed-stroke SAI cylinders cannot match. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
Because the 180 mm stroke falls below the 300 mm threshold, external side-load guides are less critical than on longer strokes, though the heavy 40 mm rod naturally resists deflection. To match this configuration exactly when replacing an ISO 15552 cylinder, specify the 160 mm bore, 180 mm stroke, 100 mm adjustment, PT ports, SUS304 (B) rod material, and the required mounting style.
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 SAIJ160BX180-100 FAQ
The rear adjuster acts as a mechanical stop that trims the effective stroke. For this model, the 180 mm nominal stroke can be reduced by up to 100 mm, creating an 80-180 mm usable travel window. It functions as a stop, not a lock, and does not hold the load without live air pressure.
At the maximum 1.0 MPa pressure, it achieves up to 2050 kgf of push force.
