About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-20
The AirTAC SAIJ80X165-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. By turning the rear stopper screw, you achieve a usable travel window of 145-165mm, allowing precise end-position tuning without swapping out hardware.
This unit features a SUS304 stainless steel rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. It supports a standard mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

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 SAIJ80BX165-20 Is Used
Product Changeover
Dial in the 145-165mm travel window during packaging line format changes to accommodate different carton sizes without changing the cylinder.
End-Stop Calibration
Fine-tune the exact retraction point during machine commissioning to prevent mechanical interference and optimize cycle timing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-20 the Right Cylinder?
The 20mm adjustment range is ideal for machine setups requiring variable end stops during product changeovers, eliminating the need to bolt on external stops or buy a fixed-stroke SAI cylinder. 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 continuous live air pressure.
When replacing an ISO 15552 cylinder, match the 80mm bore, 165mm nominal stroke, 20mm adjustment code, G3/8 PT ports, and the required mounting bracket. Although the 165mm stroke is moderate, the 25mm rod handles side loads well, though any long unsupported travel still necessitates an external guide.
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 SAIJ80BX165-20 FAQ
At its maximum 1.0MPa pressure, it can deliver up to 513kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 165mm nominal length down to 145mm. This stopper sets the travel end and works with the air cushion for deceleration, but it does not lock the load without live air.
