About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-75
It features a SUS304 stainless steel rod for superior corrosion resistance and PT tapered ports. With a nominal 210mm stroke and a 75mm adjustment range, you can dial in the exact retract end-position anywhere within a 135-210mm usable travel window during commissioning.
This adjustable stopper lets you fine-tune the machine cycle without swapping the cylinder or adding external stops. The extruded aluminum profile includes sensor grooves on both sides for flexible switch mounting. It supports a subset of ISO 15552 mounts including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ80BX210-75 Is Used
Variable End-Stop Positioning
Dial in the precise retract distance within the 135-210mm window to accommodate varying material lengths without physically remounting the actuator.
Machine Setup & Changeover
Quickly reconfigure the cylinder's effective stroke during product line changeovers by adjusting the rear stopper screw rather than replacing the whole unit.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod in light-washdown or humid assembly environments where standard carbon steel rods might degrade over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-75 the Right Cylinder?
The 75mm adjustment range is ideal for production lines running mixed product sizes, allowing rapid changeover by simply turning the rear screw. Because the stroke is 210mm, ensure an external guide supports the load to prevent excessive side-loading on the M20x1.5 rod thread.
For an exact ISO 15552 replacement, match the 80mm bore, 210mm stroke, PT port thread, and SUS304 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider the AirTAC SAIL or BSAI series instead.
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 SAIJ80BX210-75 FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke from its 210mm nominal length. You can trim the travel back by up to 75mm, creating a usable 135-210mm positioning window. It only sets the end-of-travel deceleration point and does not lock the load without continuous air pressure.
