About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-50
The AirTAC SAIJ160X165-50 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 165 mm stroke that can be dialed back by up to 50 mm, yielding a precise 115-165 mm usable travel window. In the 160 mm bore class, it delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. You can fit AirTAC CMSE reed or DMSE electronic solid-state switches if position detection is needed later, though this specific SKU ships without a magnet.

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 SAIJ160BX165-50 Is Used
Variable End-Stop Forming
Dial in the exact 115-165 mm retract depth for heavy-duty forming or pressing tasks without physically changing the actuator.
Machine Changeover
Quickly adjust the stroke up to 50 mm during product size changeovers on a packaging line to minimize downtime.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-50 the Right Cylinder?
Select this 160 mm bore actuator when an application demands high force alongside variable end-stop positioning. However, if your setup requires the full 18095 N at 0.9 MPa, this model is appropriate. The 50 mm adjustment range allows you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops, which is far more efficient than using a fixed-stroke SAI variant.
Because the stroke is 165 mm, side-load risks are moderate, but the robust 40 mm rod and M36x2 thread handle typical loads well; for long unsupported strokes, an external guide remains essential. The rear adjuster acts purely as a travel stop, not a lock, so it will not hold the load without live air. For load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.
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 SAIJ160BX165-50 FAQ
At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 165 mm down to 115 mm. This creates a 115-165 mm usable window for fine-tuning the end position at commissioning without external stops.
