About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-100
The AirTAC SAIJ160X165-100 is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, delivering robust thrust for heavy-duty tasks. It yields 14074N of push force at 0.7 MPa and up to 18095N at 0.9 MPa. A carbon steel piston rod paired with an M36x2 rod thread provides substantial rigidity, better managing side loads than smaller bores.
This specific SKU features a 165 mm nominal stroke that can be dialed back by up to 100 mm, creating a highly flexible 65-165 mm usable travel window. Unlike a fixed-stroke SAI cylinder, this rear stopper screw allows you to fine-tune the retract end-position during commissioning without adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air; for position holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-100 Is Used
Heavy Press Tuning
Dial in the exact 65 to 165 mm retract distance during precision press setups, accommodating different material thicknesses without changing the cylinder.
Product Changeovers
Quickly adjust the end-stop for varying product sizes on a high-force assembly line, minimizing downtime between production runs.
Machine Commissioning
Fine-tune the final retract position during initial machine commissioning to perfectly align heavy tooling without fabricating custom spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-100 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 14074N push force at 0.7 MPa, stepping up from a 125 mm bore that provides 8590N. The 100 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing operators to set variable end-stops on the fly. If your setup needs true load-holding without continuous air pressure, a plain SAIJ will not suffice—you should look at the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
When integrating this model, note that it uses PT tapered port threads and a G3/4 port size. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 165 mm stroke is relatively short for this large bore, external side-load guides are less critical here than with longer strokes, but the heavy M36x2 rod still requires proper alignment to prevent premature seal 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 SAIJ160X165-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. At 0.5 MPa, it provides 10053N of push force.
The rear adjuster screw allows you to trim the effective stroke back by up to 100 mm from the 165 mm nominal length, providing a usable travel window between 65 mm and 165 mm. It functions as a mechanical stop and does not lock the load without air pressure.
