About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30
The AirTAC SAIJ160X65-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. It features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports. The integrated rear stopper allows you to fine-tune the end position without swapping out the entire unit.
With a 65mm nominal stroke and a 30mm adjustment code, this model provides a usable travel window of 35-65mm. This adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30 Is Used
Variable End Stops
Ideal for heavy pressing or clamping tasks where the exact bottom position must be dialed in within the 35-65mm travel window during initial machine setup.
Product Changeover
Allows operators to quickly adjust the retract distance for different product heights on an assembly line without changing the cylinder.
Heavy Assembly
Provides the high force needed for heavy-duty assembly operations while permitting fine-tuning of the final approach distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30 the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application requires the 10053N push force at 0.5 MPa but demands exact end-position tuning during commissioning. If your setup only needs 6136N of push force, stepping down to the 125mm bore saves space and air consumption. This adjustable model is chosen over a fixed SAI cylinder when product sizes change on the line and variable end-stops are required. Ensure your ISO 15552 replacement matches the 160mm bore, 65mm stroke, PT ports, and standard mounting options.
Since the stroke is relatively short at 65mm, side-loading is less of a concern than with longer strokes, but the robust 40mm rod diameter still handles substantial off-center loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Note that because no magnet is specified, this unit cannot use CMSE or DMSE sensors for position detection.
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 SAIJ160BX65-30 FAQ
At an operating pressure of 0.5 MPa, this 160mm bore cylinder provides a push force of 10053N and a pull force of 9425N. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 65mm nominal stroke by up to 30mm, creating a usable travel window of 35-65mm. It only sets the end position and does not lock the load without live air pressure.
