About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-10
The AirTAC SAIJ80X450-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 440 to 450mm, letting you dial in the exact retract position during commissioning.
This variant uses an SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads with a G3/8 connection. Because the stroke extends to 450mm, the 25mm rod diameter should be paired with an external guide to prevent excessive side-loading on the extruded aluminum barrel.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-10 Is Used
Machine Setup Calibration
Fine-tune the 440 to 450mm retract position during initial commissioning to achieve precise end-stop alignment without machining new spacer blocks.
Product Size Changeover
Quickly adjust the stroke end by up to 10mm on packaging lines when switching between slightly different product dimensions.
Long-Stroke Forming
Leverage the 2513N push force for light forming tasks, using the rear stopper to set exact material engagement depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-10 the Right Cylinder?
Choose this 80mm bore when an application requires more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but less bulk than a 100mm unit. The 10mm adjustment range is ideal for fine-tuning end stops during machine setup or product changeovers, replacing the need to physically swap out a fixed-stroke SAI cylinder.
When integrating this model, remember the rear adjuster acts only as a travel stop and does not hold the load without continuous air pressure. For true load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 component, it shares the standard mounting footprint but utilizes a reduced SAIJ bracket set: 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 SAIJ80AX450-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 450mm stroke by up to 10mm, creating a 440 to 450mm travel window. It only sets the end position and does not lock the load without live air pressure.
