About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-10
The AirTAC SAIJ80X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 145 to 155 mm, letting you dial in the exact end-stop without adding external stops. It delivers robust force, pushing 4523 N at 0.9 MPa and 2513 N at 0.5 MPa.
This model is equipped with a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE solid-state switches if a magnet is added later. It supports a speed range of 30-800 mm/s and features variable air cushions at both ends to manage deceleration.

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 SAIJ80AX155-10 Is Used
Machine Commissioning
Fine-tune the 145-155 mm travel window during initial setup to perfectly align tooling without machining custom spacers.
Product Changeover
Quickly adjust the retract end-stop on packaging lines when switching between different package sizes.
End-Stop Trimming
Trim the effective stroke by up to 10 mm to compensate for mechanical wear or slight misalignments over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-10 the Right Cylinder?
The 10 mm adjustment range is ideal for machine setups requiring precise end-position tuning during commissioning or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder.
When matching this ISO 15552 cylinder, specify the 80 mm bore, 155 mm stroke, 10 mm adjustment, PT port thread, and the SUS420J2 rod material. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an external rod lock or the SAIL series.
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 SAIJ80AX155-10 FAQ
At 0.5 MPa, the push force is 2513 N.
A rear adjusting screw acts as an external stopper, allowing you to shorten the nominal 155 mm stroke by up to 10 mm. This creates a usable travel window of 145 to 155 mm, which can be fine-tuned during commissioning without replacing the cylinder.
