About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-100S
The AirTAC SAIJ80X150-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in -100 adjustment mechanism allows you to dial back the nominal 150mm travel, providing a flexible 50-150mm usable window for precise end-position tuning during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It supports AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves. The rear adjuster acts purely as a mechanical stop to set the travel end; it 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 SAIJ80BX150-100S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point between 50 and 150mm during machine commissioning to perfect product positioning without machining new hard stops.
Product Size Changeover
Quickly adapt actuator travel on packaging lines handling different carton sizes by adjusting the rear screw rather than replacing the entire cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-100S the Right Cylinder?
The 50-150mm adjustable window is highly advantageous for machines that undergo frequent product changeovers, allowing operators to set variable end-stops without physically swapping the cylinder or adding external stopper blocks. For true load-holding without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 80mm bore, 150mm nominal stroke, 100mm adjustment range, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this unit features a 25mm rod and M20x1.5 thread, it handles side loads well, though any stroke over 300mm would require 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 SAIJ80BX150-100S FAQ
The rear adjuster is a mechanical stop that lets you shorten the effective stroke by up to 100mm. This creates a usable travel window of 50-150mm, allowing fine-tuning of the end position at commissioning. It does not lock the load without live air pressure.
It operates at speeds between 30 and 800 mm/s.
