About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-20
The AirTAC SAIJ80X600-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 580-600mm usable travel window, allowing you to dial back the 600mm nominal stroke by up to 20mm during commissioning. The standard extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant uses a SUS304 stainless steel piston rod (code B) for superior corrosion resistance. It features PT tapered port threads (G3/8) and variable air cushions at both ends to manage deceleration. The rear adjuster acts purely as a mechanical stop, meaning it will not hold a load without live air pressure.

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 SAIJ80BX600-20 Is Used
Equipment Changeover
Fine-tune the 580-600mm retract position on packaging lines when swapping product sizes, avoiding the need to physically remount the cylinder.
End-Stop Calibration
Dial in the exact bottoming position during machine commissioning, using the rear screw to absorb mechanical tolerances without adding external stoppers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-20 the Right Cylinder?
The 20mm adjustment range is ideal for product changeovers, letting you fine-tune the retract position without swapping cylinders or adding external stops. For true load-holding without live pressure, consider the SAIL or BSAI series instead.
With a 600mm stroke, the M20x1.5 rod is highly susceptible to side-loading. An external guide rail is strongly recommended to prevent premature seal wear and binding. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX600-20 FAQ
The rear adjuster is a mechanical stop that shortens the effective travel from 600mm down to 580mm. It allows precise end-position tuning during setup but does not lock the load without live air pressure.
