About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-30
The AirTAC SAIJ80X135-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This unit is configured with an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features PT tapered port threads. The rear stopper acts purely as a travel limit for commissioning fine-tunes, meaning it cannot hold a load without continuous live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80AX135-30 Is Used
Product Changeover
Quickly adapt retract distances on a packaging line when switching to a different package size, using the 30mm adjustment window to avoid changing cylinders.
Machine Setup Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfectly time a pressing or lifting operation without adding external mechanical stops.
Variable End-Stop Clamping
Provide adjustable clamping reach on an assembly fixture, allowing operators to modify the 105-135mm travel window based on the specific workpiece dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-30 the Right Cylinder?
Select this 80mm bore when an application requires substantial force but demands precise end-position tuning during machine setup or product changeover. Because this is an adjustable-stroke model, you can trim the 135mm nominal travel back by up to 30mm on-site, avoiding the need to inventory multiple fixed-stroke SAI cylinders.
For a true ISO 15552 replacement match, verify the 80mm bore, 135mm stroke, -30 adjustment, PT port thread, and your preferred mounting accessory. SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the SAIJ series omits FB, CA, CB, and CR mounts entirely. If your machine requires positive load-holding without air pressure, you must integrate an external rod lock or look at the SAIL or BSAI series instead.
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 SAIJ80AX135-30 FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the nominal 135mm stroke by up to 30mm, creating a usable travel window of 105 to 135mm. This stopper only limits travel; it does not lock the load without live air pressure.
