About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-40
The AirTAC SAIJ80X160-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 160 mm travel back by up to 40 mm, creating a precise 120-160 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered ports. The 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity, meaning the piston rod can accommodate higher side loads than smaller bores, though an external guide is still recommended for heavy lateral forces. The rear adjuster acts strictly as a travel stop to set the retract position, not as a lock to hold the load without live 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 SAIJ80BX160-40 Is Used
Machine Commissioning
Dial in the exact 120 to 160 mm retract position during setup without machining custom spacers or swapping cylinders.
Product Changeover
Quickly adjust the stroke end-stop to accommodate varying package sizes on a packaging line.
End-Stop Tuning
Fine-tune the final retract position to achieve precise mechanical alignment without adding external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-40 the Right Cylinder?
Select this 80 mm bore model when your application requires substantial thrust—stepping down to a 63 mm bore reduces the 0.5 MPa push force to 1559 N, whereas the SAIJ80X160-40 provides 2513 N. The 40 mm adjustment range is particularly useful during machine commissioning or product changeovers, allowing you to dial in the exact retract distance without swapping out the entire cylinder or machining custom spacers. For fixed-length applications that never require end-position tuning, a standard SAI cylinder would suffice.
When replacing an ISO 15552 cylinder, verify the 80 mm bore, 160 mm stroke, 40 mm adjustment requirement, PT port thread, and the desired mounting style. SAIJ supports a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. Because the stroke is under 300 mm, side-load concerns are manageable, but always ensure the load is guided to prevent rod binding. If the machine requires true load-holding in the event of air loss, note that the SAIJ adjuster cannot hold the load; you should look at the SAIL or BSAI series instead.

- ✓ 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 SAIJ80BX160-40 FAQ
The 160 mm nominal stroke can be adjusted back by up to 40 mm, providing a usable travel window of 120 to 160 mm.
No, the rear adjuster functions only as a mechanical travel stop to fine-tune the end position and does not lock the load. For load-holding without live air pressure, consider the AirTAC SAIL or BSAI cylinder series.
