About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10
The AirTAC SAIJ80X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 465-475mm usable travel window. Delivering 2513N of push force at 0.5 MPa, it handles demanding positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads. The rear stopper allows precise end-position tuning during commissioning without adding external stops. Note that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10 Is Used
Changeover Calibration
Dial in the exact 465-475mm retract position during machine setup to accommodate new product dimensions without changing hardware.
End-Stop Trimming
Fine-tune the final deceleration point on long-stroke assembly presses to prevent mechanical crashing and ensure precise component seating.
Variable Diverting
Adjust the stroke length on the fly for pneumatic diverters that must handle varying package sizes on a single conveyor line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10 the Right Cylinder?
Choose this 80mm bore when a 50mm cylinder (982N push at 0.5 MPa) lacks thrust or a 100mm bore (3927N) is excessive. The 10mm adjustment window is ideal for fine-tuning the retract position on product changeovers rather than swapping a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, verify the 475mm stroke, PT ports, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 475mm, an external guide is recommended to prevent excessive rod side-loading. If true load-holding is required without live air, select a SAIL or BSAI cylinder instead of relying on the stopper.
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 SAIJ80AX475-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 475mm stroke by up to 10mm, creating a 465-475mm travel window. It sets the end position but does not lock the load without continuous air pressure.
