About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-75S
The AirTAC SAIJ80X165-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 165 mm stroke that can be dialed back by up to 75 mm, creating a usable travel window of 90 to 165 mm for exact end-position tuning. Delivering a pull force of 2268 N at 0.5 MPa, it handles heavy loads while using a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet works seamlessly with CMSE reed and DMSE electronic sensors mounted in the dual-side barrel grooves.
This adjustable model lets you fine-tune the retract end at commissioning without adding external stops or swapping cylinders. The rear screw acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an external rod lock or the SAIL series. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The PT tapered port threads ensure a robust, leak-free pneumatic connection.

Theoretical Output Force (Ø80mm)

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 SAIJ80 Adjustable Cylinder SAIJ80BX165-75S Is Used
Variable End-Stop Tuning
Dial in the retract position anywhere from 90 to 165 mm during commissioning to perfectly set the resting height of a press or clamp without changing the cylinder.
Product Size Changeover
Quickly adapt a conveyor diverter arm to handle different package lengths by adjusting the rear stopper up to 75 mm, eliminating the need for custom spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-75S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust, such as the 2268 N pull force at 0.5 MPa, but still needs the flexibility of a variable end-stop. If your force requirements are lower, stepping down to a 63 mm bore provides 1402 N of pull force at 0.5 MPa. The 75 mm adjustment range is ideal for machines processing varying product sizes, allowing rapid changeover without hardware swaps. For load-holding without live air pressure, select the SAIL or BSAI clamp-lock cylinders instead of relying on the SAIJ adjuster.
As a direct ISO 15552 replacement, match the 80 mm bore, 165 mm stroke, 75 mm adjustment, PT ports, and -S magnet to ensure dimensional interchangeability. The 25 mm rod diameter and M20x1.5 thread handle high side loads well, but because the stroke is 165 mm, always use an external guide for heavy or off-center loads to prevent rod binding.

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 SAIJ80 Adjustable Cylinder SAIJ80BX165-75S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 165 mm down to 90 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
