About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-10
The AirTAC SAIJ80X120-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning during commissioning. It provides a usable travel window of 110 to 120 mm, allowing you to dial back the 120 mm nominal stroke by up to 10 mm without adding external stops.
This variant features a SUS304 stainless steel rod for corrosion resistance and uses an extruded aluminum barrel with sensor grooves on both sides. The rear adjuster acts purely as a travel stop and works alongside the variable air cushions to decelerate the load; it does not hold the load without live air pressure. For position holding, explore the SAIL or BSAI series.

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 SAIJ80BX120-10 Is Used
Machine Setup Tuning
Dial in the exact 110-120 mm retract position during initial commissioning without swapping cylinders or machining external stopper blocks.
Product Changeover
Quickly adjust the end-stop to accommodate slight variations in product size on a packaging line, reducing downtime between runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX120-10 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the thrust for your application but a 100 mm bore is excessive. The 10 mm adjustment range is ideal for fine-tuning the retract end position during machine setup or product changeover, replacing the fixed stroke of a standard SAI cylinder. To replace an ISO 15552 cylinder, match the 80 mm bore, 120 mm stroke, 10 mm adjuster, PT G3/8 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts. Because the stroke is under 300 mm, side-load risks are minimal, but long unsupported loads still need 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 SAIJ80BX120-10 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 110 to 120 mm. The adjuster acts as a mechanical stop to set the retract position and does not lock the load without live air pressure.
It can deliver up to 513 kgf at its maximum operating pressure of 1.0 MPa.
