About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-10S
The AirTAC SAIJ80X120-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 110-120 mm. The barrel is machined from extruded aluminum and includes sensor grooves on both sides.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston for position detection. The rear adjuster acts purely as a mechanical stop to set the end position and does not lock the load without live air pressure. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX120-10S Is Used
Machine Changeover
Dial in the exact 110-120 mm end-stop during product size changes without physically replacing the cylinder or reworking mounting plates.
Corrosive Assembly Lines
Utilize the SUS304 stainless steel rod in humid or washdown assembly environments while tracking piston position with DMSE solid-state sensors.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-10S the Right Cylinder?
Choose this 80 mm bore when you need significantly more force than the 50 mm option (which provides 982 N at 0.5 MPa) but want to avoid the larger footprint of a 100 mm cylinder. The adjustable 10 mm trim is ideal for precise commissioning without swapping cylinders or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 120 mm nominal stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet requirement. The 25 mm rod and M20x1.5 thread provide excellent side-load capacity, though any stroke over 300 mm would still 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 SAIJ80BX120-10S FAQ
The maximum push force reaches 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 120 mm stroke by up to 10 mm, creating a usable travel window of 110-120 mm. It functions as a travel stop for end-position tuning and does not hold the load without live air.
