About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-40
The AirTAC SAIJ80X135-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 95-135mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic switches.
This model uses a PT tapered G3/8 port and a 25mm rod with an M20x1.5 thread. The rear stopper mechanism allows you to fine-tune the end position at commissioning without adding external stops. It supports a reduced mounting set including 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 SAIJ80AX135-40 Is Used
Machine Changeover
Dial in the exact 95 to 135mm end position when switching between product sizes on a packaging line without swapping the cylinder.
End-Position Tuning
Fine-tune the retract stroke during commissioning to absorb mechanical tolerances and achieve precise end-stop alignment.
Variable End Stops
Use the rear screw to set a specific travel limit for delicate pressing or clamping operations within the 40mm window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-40 the Right Cylinder?
Select this 80mm bore cylinder when an application requires trimming the travel from 135mm down to 95mm during product changeovers. If your setup needs less thrust, stepping down to a 63mm bore yields 1559N at 0.5MPa. For heavier loads, a 100mm bore provides 3927N. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 footprint, specify the 80mm bore, 135mm stroke, 40mm adjustment, PT G3/8 port, and SUS420J2 rod.
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 SAIJ80AX135-40 FAQ
A rear external screw acts as a stopper, allowing you to shorten the effective stroke by up to 40mm. This creates a usable travel window of 95 to 135mm without altering the cylinder mounting.
At the maximum 1.0MPa pressure, the push force reaches 4523N.
