About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-20S
The AirTAC SAIJ80X170-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 150-170 mm, allowing you to dial back the 170 mm nominal stroke by up to 20 mm during machine commissioning.
This specific SKU is built with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in washdown or chemically active environments. It features PT tapered port threads (G3/8) and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable stopper functions purely as an end-position setter, not a load-holding lock.

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 SAIJ80BX170-20S Is Used
Machine Setup Tuning
Dial in the exact 150-170 mm end-stop during initial commissioning to perfect tooling engagement without machining custom spacers.
Product Changeover
Quickly retract the stroke by up to 20 mm on automated lines when switching to a slightly shorter product variant.
Washdown Positioning
Leverage the SUS304 stainless steel rod for heavy-duty actuation in food processing or chemical manufacturing environments requiring frequent washdowns.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-20S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end-position without swapping cylinders or adding external stops. For any load-holding requirements without continuous live air pressure, this cylinder's rear adjuster will not suffice; you should instead look at the SAIL pneumatic lock or BSAI clamp-lock series. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ80BX170-20S FAQ
At the maximum 1.0 MPa pressure, it provides up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 170 mm nominal stroke, providing a usable travel window of 150 to 170 mm. It only sets the end-position and does not lock the load without live air pressure.
