About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-40S
The AirTAC SAIJ80X170-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear screw, you can trim the effective travel anywhere within a 130 to 170mm window, giving you exact end-position control without swapping out hardware.
This unit includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the sensor grooves on both sides of the extruded aluminum barrel. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance. It carries the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR options.

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 SAIJ80BX170-40S Is Used
Product Changeovers
Dial in the 130 to 170mm travel window during format changes on a packaging line, using the rear screw to set new end positions instantly without changing the cylinder.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to achieve precise mechanical alignment, avoiding the need to add external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-40S the Right Cylinder?
The 40mm adjustment range is perfect for product-size changeovers on a packaging line, letting you dial in the exact 130 to 170mm end-stop on the fly. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device; it will not hold a load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder.
To match this exact ISO 15552 interchangeable cylinder, specify an 80mm bore, 170mm stroke, 40mm adjustment, PT port thread, SUS304 rod material, and the -S magnet option. Because the nominal stroke is 170mm, side-load stress is moderate, but ensuring proper external guiding will maximize seal life.
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 SAIJ80 Adjustable Cylinder SAIJ80BX170-40S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster acts as an external stopper that allows you to shorten the 170mm nominal stroke by up to 40mm, creating a usable travel window of 130 to 170mm. It only sets the travel end and does not lock the load without continuous air pressure.
