About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-75
The AirTAC SAIJ80X165-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 90 mm from the 165 mm nominal stroke. This on-machine variability eliminates the need to swap barrels or bolt on external stops during product changeovers.
Built for demanding environments, this variant incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance. The fluid porting utilizes a PT tapered G3/8 thread, and the extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop to work alongside the variable air cushions; it does not lock or hold the load without continuous air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX165-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 90-165 mm window during commissioning without physically swapping out the cylinder for a different stroke length.
Product Size Changeover
Quickly adapt machinery on a mixed-product line by adjusting the rear stopper up to 75 mm to accommodate different package dimensions on the fly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable thrust in washdown or chemically exposed manufacturing areas where carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-75 the Right Cylinder?
Choose this 80 mm bore when your application requires higher thrust than a 63 mm cylinder (which provides 1559 N at 0.5 MPa) but does not warrant the larger footprint of a 100 mm unit. The 75 mm adjustment range is particularly useful for prototyping or lines running mixed product sizes, allowing you to dial in the exact end-position without replacing the actuator. For operations requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, 75 mm adjustment, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 25 mm rod and M20x1.5 thread handle substantial side loads, ensure your mounting configuration properly supports the rod end, especially since the usable stroke can extend up to 165 mm.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80BX165-75 FAQ
If you increase the pressure to 0.9 MPa, the push force reaches 4523 N.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the 165 mm nominal stroke down to a minimum of 90 mm. It works with the air cushions to set the end position but does not lock the load without live air pressure.
