About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-30
The AirTAC SAIJ80X150-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 120 to 150 mm, allowing you to dial back the nominal 150 mm stroke by up to 30 mm during commissioning. In this configuration, the rod is crafted from SUS304 stainless steel (code B), and the pneumatic connections use PT tapered threads.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Remember that the rear adjuster acts purely as a mechanical stop for end-position tuning; it does not lock or hold the load without continuous 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 SAIJ80BX150-30 Is Used
Machine Changeover
Dial in the 120-150 mm travel window during product size changes to set precise end positions without swapping cylinders.
Variable End Stops
Use the rear adjuster to accommodate different package sizes on a packaging line, providing flexible stopping points.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-30 the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires high force combined with variable end stops. The adjustable stroke is ideal for machine setups requiring fine-tuning without adding external stops or swapping components.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 150 mm stroke, 30 mm adjustment, PT port threads, and SUS304 rod material. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. For load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ80BX150-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 150 mm down to 120 mm. It only sets the travel end and does not hold the load without live air pressure.
