About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-100
The AirTAC SAIJ80X135-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 135 mm travel by up to 100 mm. This creates a highly versatile usable stroke window of 35 to 135 mm, perfect for adapting machinery to varying product sizes without physically swapping the actuator.
This specific SKU is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes dual sensor grooves, though this unit is supplied without a magnet. It is important to note that the rear adjuster functions strictly as a travel stop for end-position tuning, not as a locking device; it cannot hold a load without continuous 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 SAIJ80AX135-100 Is Used
Product Changeovers
Quickly adapt to different package lengths on a packaging line by dialing in the exact stroke from 35 to 135 mm without changing hardware.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to achieve precise mechanical alignment without adding external stopper blocks.
Variable End Stops
Handle diverse part sizes in automated clamping stations by adjusting the retraction point on the fly to suit each specific workpiece.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX135-100 the Right Cylinder?
The generous 100 mm adjustment range is ideal for machines that undergo frequent product changeovers, eliminating the need to add external stops.
When integrating this cylinder, ensure your setup matches the exact configuration: an 80 mm bore, 135 mm nominal stroke, 100 mm adjustment, PT G3/8 port, and no magnet. Mounting options are limited to the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. Because the 135 mm stroke is relatively short, side-load risks are minimal, but the 25 mm rod and M20x1.5 thread still provide excellent rigidity. For any load-holding requirements without live air, you must use an external rod lock or pilot-operated check valve, as the adjuster only decelerates the travel end.
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 SAIJ80AX135-100 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster acts as a stopper that lets you trim the effective travel back by up to 100 mm. This turns the 135 mm nominal stroke into a usable window of 35 to 135 mm, allowing you to set the exact end position at commissioning. It is a travel stop, not a lock.
