About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-30
The AirTAC SAIJ80X165-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 135-165 mm usable travel window, letting you dial back the 165 mm nominal stroke by up to 30 mm during commissioning.
This model incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered ports for secure pneumatic connections. The extruded aluminum barrel includes dual sensor grooves, supporting AirTAC CMSE reed and DMSE electronic sensors for flexible position monitoring. The rear adjuster acts purely as a mechanical stop to set the end position and does not 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 SAIJ80BX165-30 Is Used
Machine Changeover
Fine-tune the 135-165 mm travel window during product size changes without bolting on external physical stops.
End-Position Tuning
Dial in the exact retract stroke at commissioning using the rear screw, ensuring precise mechanical positioning.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in wash-down or mildly corrosive industrial settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-30 the Right Cylinder?
The 30 mm adjustment window is ideal for product changeovers, allowing variable end-stops without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI locking cylinder series instead of relying on the adjuster. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ80BX165-30 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the 165 mm nominal stroke by up to 30 mm, giving an effective travel range of 135-165 mm. It sets the end position but does not lock or hold the load without live air pressure.
It operates at speeds of 30-800 mm/s.
