About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30
The AirTAC SAIJ80X60-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 30 to 60 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it utilizes a robust 25 mm piston rod with an M20x1.5 thread to handle high side loads effectively. This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads.
You can fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The rear adjuster acts strictly as a travel stop and works alongside variable air cushions at both ends, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30 Is Used
Precision Position Tuning
Dial in the exact retract distance within the 30 to 60 mm window during machine commissioning to achieve perfect alignment without external stopper hardware.
Product Size Changeover
Quickly adapt end-of-stroke positions on packaging lines when handling different product heights, utilizing the 30 mm adjustment range for rapid format changes.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod in humid or washdown manufacturing environments where standard carbon steel rods would degrade over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30 the Right Cylinder?
Select this 80 mm bore when an application requires more force than a 63 mm cylinder, which provides 1559 N of push force at 0.5 MPa, but less than the 3927 N generated by a 100 mm unit. The adjustable stroke is perfect for machine setups requiring variable end stops or product-size changeovers, giving you a 30 mm trimming range on a 60 mm nominal stroke. Since this is an adjustable-stroke model, it uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
To match this exact replacement, verify the 80 mm bore, 60 mm nominal stroke, 30 mm adjustment range, PT port threads, and the SUS304 stainless steel rod material. Note that this unit lacks a magnet, so it is not compatible with CMSE or DMSE sensors without a model suffix change.
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 SAIJ80BX60-30 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm from the 60 mm nominal length, creating a 30 to 60 mm travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
