About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100
The AirTAC SAIJ80X600-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 500-600mm usable travel window. Delivering 2513N of pull force at 0.5 MPa, it handles heavy loads with precision. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered port thread. The rear stopper allows you to fine-tune the end position during commissioning without adding external stops. The adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100 Is Used
Product Size Changeover
Dial the stroke back by up to 100mm to accommodate varying package sizes on a packaging line without changing the cylinder.
Commissioning Fine-Tune
Precisely set the retract end-position during machine setup to avoid mechanical interference and optimize motion.
Variable End-Stop Machining
Use the adjustable travel window to set different material feed lengths directly at the rear stopper screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100 the Right Cylinder?
Choose this 80mm bore when you need substantial thrust, such as the 2513N pull force at 0.5 MPa, stepping up from a 63mm bore that provides 1402N. The 100mm adjustment range is ideal for product-size changeovers on a line, allowing you to dial back the 600mm stroke precisely to 500mm without swapping the cylinder.
Because the 600mm stroke is long, the 25mm rod diameter still requires an external guide to prevent excessive side loading on the bearings. For load-holding without live air, this plain cylinder is insufficient; consider the SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. ISO 15552 interchangeability ensures easy replacement using the 80mm bore, 600mm stroke, PT port, and standard mounting dimensions.

- ✓ 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 SAIJ80BX600-100 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the 600mm nominal stroke by up to 100mm, resulting in a 500-600mm usable travel window. It sets the end position but does not lock the load without live air.
At 0.5 MPa, it provides 2513N of pull force and 3518N of push force. At 0.7 MPa, the push force increases to 3518N.
