About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-40
The AirTAC SAIJ80X600-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 600 mm travel that can be mechanically trimmed back by up to 40 mm, yielding a precise 560 to 600 mm usable window. This bore size delivers substantial thrust, pushing 4523 N at 0.9 MPa, making it well-suited for heavy actuation tasks.
This specific unit is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, though this non-magnet version requires adding an -S suffix to the SKU if CMSE reed or DMSE electronic sensors are needed for position detection.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-40 Is Used
Variable End-Stop Machining
Dial in the exact 560 to 600 mm retract position for multi-format machining fixtures without disassembling the pneumatic line.
Product Size Changeovers
Quickly adapt a heavy-duty conveyor diverter arm to accommodate varying package lengths on the fly using the 40 mm adjustment screw.
Heavy Assembly Setup
Leverage the 4523 N push force to press large components while fine-tuning the final clamping position during initial machine commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-40 the Right Cylinder?
Choose this 80 mm bore when an application requires pushing forces around 4523 N at 0.9 MPa, stepping up from a 63 mm bore that provides 2805 N. The 40 mm rear adjustment screw is ideal for fine-tuning the retract end position during commissioning or product changeovers without physically swapping the cylinder or adding external stops. It is important to note the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead.
Because the 600 mm stroke exceeds the 300 mm threshold, an external guide is strongly recommended to prevent excessive side-loading on the 25 mm rod. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, omitting FB, CA, CB, and CR options. To replicate this exact setup, specify a PT port, SUS420J2 rod material, no magnet, and a 600 mm stroke with a 40 mm adjustment range.

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 SAIJ80AX600-40 FAQ
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates a push force of 4523 N and a pull force of 3681 N. It can achieve a maximum push force of 513 kgf at 1.0 MPa.
The rear stopper screw allows you to shorten the effective travel from the nominal 600 mm down to 560 mm. This provides a 40 mm adjustable window for setting precise end-positions at commissioning without altering the physical cylinder mount.
