About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-75
The AirTAC SAIJ80X475-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 400 to 475 mm. It delivers a 0.5 MPa push force of 2513 N, utilizing a G3/8 port and a 25 mm piston rod. The rod is constructed from SUS420J2 stainless steel, offering enhanced durability against moisture and minor side-load wear compared to standard carbon steel.
This adjustable model allows operators to dial in the retract end-position precisely during commissioning without adding external stops. It includes variable air cushions at both ends with a 36 mm stroke length, and the extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE or DMSE switches.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-75 Is Used
Product Changeover Adjustment
Dial in the retract stroke from 400 to 475 mm during line changeovers to accommodate varying product lengths without swapping the cylinder.
End-Position Calibration
Fine-tune the final end-stop during machine commissioning to perfect positioning without fabricating external shim plates.
Variable Length Diverter
Act as a diverter on a conveyor handling mixed-size packages, adjusting the pusher travel window to match specific item dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-75 the Right Cylinder?
Choose this 80 mm bore when your application requires the 2513 N push force at 0.5 MPa, which sits between the 63 mm bore (1559 N) and the 100 mm bore (3927 N). The 75 mm adjustment range is highly effective for product changeovers, allowing you to shorten the stroke from 475 mm down to 400 mm on the fly. Because the nominal 475 mm stroke is long, an external guide is recommended to prevent excessive rod deflection and premature seal wear.
For fixed travel needs without commissioning adjustments, the standard SAI series is sufficient. Note that the rear adjuster acts only as a travel stop and provides no load-holding capability without live air pressure; for true fail-safe holding, consider the SAIL or BSAI series. This SKU uses PT tapered ports and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.
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 SAIJ80AX475-75 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster stopper allows you to mechanically shorten the effective stroke from its nominal 475 mm down to 400 mm. It functions as an end-stop for position tuning and does not lock the load without live air pressure.
