About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-75
The AirTAC SAIJ80X155-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80 to 155 mm. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and utilizes a PT tapered port thread. The rear screw mechanism acts purely as a travel stop for end-position tuning during commissioning; it does not hold the load without live air pressure. For load-holding requirements, external rod locks or related series like SAIL or BSAI should be considered.

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 SAIJ80AX155-75 Is Used
Variable End-Stops
Ideal for production lines running mixed product sizes, allowing the effective stroke to be shortened dynamically from 155 mm down to 80 mm via the rear adjuster during changeovers.
Commissioning Fine-Tuning
Enables precise end-position calibration at machine setup without physically repositioning the cylinder or fabricating custom external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-75 the Right Cylinder?
The 75 mm adjustment range is ideal for machines handling frequent product-size changeovers, allowing operators to dial in the exact end-stop without swapping the cylinder or adding external physical stops. It supports a speed range of 30-800 mm/s.
As a dimensionally interchangeable ISO 15552 profile cylinder, it shares the exact mounting footprint of standard ISO cylinders. Available mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 25 mm rod diameter and M20x1.5 thread provide robust side-load resistance, though any application approaching or exceeding 300 mm of total travel should still incorporate an external guide to protect the rod seal.
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 SAIJ80AX155-75 FAQ
At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that can trim the effective travel back by up to 75 mm from the nominal 155 mm stroke, creating an 80 to 155 mm usable window. It decelerates the travel end but does not lock or hold the load without continuous air pressure.
