About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-50
The AirTAC SAIJ80X180-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down from 180 mm to a 130-180 mm range. This bore size uses a G3/8 port and a 36 mm cushion to manage end-of-stroke energy.
Equipped with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this unit is built for durability. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE solid-state sensors if position feedback is needed later.

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 SAIJ80AX180-50 Is Used
Machine Changeovers
Dial in the exact end-stop during product size changeovers without swapping the cylinder or adding external mechanical stops.
Stroke Fine-Tuning
Trim the 180 mm nominal travel back by up to 50 mm to perfectly time the press or clamping motion at commissioning.
Variable End Positioning
Set precise retract positions on automated lines where multiple product sizes require slightly different stroke lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-50 the Right Cylinder?
The 50 mm adjustment range is ideal for machine changeovers, letting you dial in the exact end position without swapping hardware or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true drop-prevention, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard bore, stroke, PT port, and mounting footprints.
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 SAIJ80AX180-50 FAQ
The rear adjuster screw lets you shorten the effective stroke from its 180 mm nominal length by up to 50 mm, providing a usable travel window of 130 to 180 mm. The adjuster acts as a physical stop and works with the 36 mm air cushion to decelerate the load, but it does not lock the position without live air pressure.
At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
