About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-10
The AirTAC SAIJ80X135-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated adjustment screw allows you to trim the effective travel back by up to 10mm, creating a precise 125-135mm usable stroke window without needing external stops.
This variant features an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. The rear adjuster functions strictly as a travel stop for end-position tuning and does not lock the load without live air pressure.

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 SAIJ80AX135-10 Is Used
Machine Changeover
Dial in the 125-135mm travel window during product size changes to set precise end positions without machining new hard stops.
Commissioning Calibration
Fine-tune the retract stroke up to 10mm during initial setup to perfectly seat parts, avoiding the cost of custom fixed-stroke cylinders.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-10 the Right Cylinder?
The adjustable 125-135mm travel window is ideal for machine setups requiring exact end-position calibration during commissioning or product changeovers, replacing the need to swap out a fixed-stroke SAI cylinder. When matching an ISO 15552 replacement, verify the 80mm bore, 135mm stroke, 10mm adjustment, PT G3/8 port, and mounting style. Since this is a plain SAIJ without a magnet, position sensing is not supported out of the box.
For any stroke at or above 135mm, ensure external guides are used to support the load. The 25mm rod and M20x1.5 rod thread handle side loads well, but the rear adjuster and air cushions only decelerate the travel end. They do not hold the load pneumatically; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX135-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 135mm nominal stroke by up to 10mm. This creates a 125-135mm usable travel window for fine-tuning end positions without altering the cylinder mount.
