About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10
The AirTAC SAIJ80X75-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 75 mm stroke that can be fine-tuned down by up to 10 mm, creating a precise 65-75 mm usable travel window for exact end-position calibration. Delivering 2513 N of push force at 0.5 MPa, it fits robustly into medium-to-heavy automation tasks.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes dual-side sensor grooves for mounting position switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster acts strictly as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10 Is Used
Machine Setup and Changeover
Dial in the exact 65-75 mm retract position during product size changes without physically swapping out cylinders or re-engineering external stopper blocks.
End-Position Tuning
Fine-tune the final retract distance by up to 10 mm during commissioning to accommodate mechanical tolerances and ensure precise tool alignment.
Variable End-Stop Automation
Implement a flexible mechanical stop in medium-force assembly lines where the 2513 N push force at 0.5 MPa is sufficient for pressing or clamping operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10 the Right Cylinder?
Choose this 80 mm bore when your application requires the 2513 N push force at 0.5 MPa (or 3518 N at 0.7 MPa) and a highly specific end-position within a 65-75 mm window. If your thrust requirements are lower, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the exact retract position without swapping the cylinder or adding external stops.
Because the stroke is 75 mm, side-load risks are minimal, but always ensure proper rod alignment. If your process demands true load-holding without continuous live air, note that this cylinder's adjuster is a stop, not a lock; you should instead consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. For ISO 15552 dimensional interchangeability, match the 80 mm bore, 75 mm stroke, 10 mm adjustment, PT port thread, and your required mounting accessory.

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 SAIJ80AX75-10 FAQ
At 0.5 MPa operating pressure, the 80 mm bore provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 75 mm stroke by up to 10 mm, providing an adjustable travel window of 65 to 75 mm. It sets the end position but does not lock or hold the load without live air pressure.
