About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-50S
The AirTAC SAIJ80X175-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 175 mm nominal travel by up to 50 mm. This yields a precise 125-175 mm usable positioning window during commissioning without requiring external stops.
This SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a built-in magnet for CMSE and DMSE sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the rear adjuster acts purely as a travel stop for end-position tuning rather than a load-holding lock.

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 SAIJ80AX175-50S Is Used
Product Changeover
Quickly modify the 125-175 mm travel window on packaging lines to accommodate different carton sizes without swapping out the entire cylinder assembly.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to prevent mechanical crashes, using the rear stopper to perfect the final resting position.
Variable End Stops
Provide adjustable physical stops for assembly presses requiring precise 80 mm bore thrust (up to 4523 N at 0.9 MPa) across varying material thicknesses.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-50S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. For holding loads without live air pressure, you must integrate an external pilot-operated check valve or select a different series like SAIL or BSAI, as the SAIJ adjuster is only a stop.
To match this exact configuration for an ISO 15552 replacement, specify the 80 mm bore, 175 mm stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the 175 mm stroke is under the 300 mm threshold, side-load stress is manageable, but always ensure the M20x1.5 rod thread is properly aligned to maximize bearing life.
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 SAIJ80AX175-50S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster allows you to shorten the 175 mm nominal stroke by up to 50 mm, creating a usable travel window of 125 to 175 mm. This mechanism acts as a physical stop to tune the end position and does not lock the load without continuous air pressure.
