About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-30S
The AirTAC SAIJ80X475-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 445 to 475 mm. Delivering 2513 N of push force at 0.5 MPa, it handles substantial pneumatic workloads. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual sensor grooves.
This specific configuration features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. Because the stroke reaches 475 mm, the M20x1.5 rod thread and 25 mm rod diameter should be paired with an external guide to manage side loading on the extended axis.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-30S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 445-475 mm window during machine setup, allowing precise positioning without machining external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when transitioning between different product sizes, minimizing downtime.
Long-Stroke Positioning
Leverage the 2513 N push force at 0.5 MPa over a 475 mm travel distance, using the 30 mm adjuster to fine-tune the final end position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-30S the Right Cylinder?
Select this 80 mm bore when an application requires more power than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the bulk of a 100 mm unit (3927 N). The 30 mm adjustment range is ideal for fine-tuning the retract end position during machine commissioning or product changeovers without swapping hardware. To match this exact configuration for an ISO 15552 replacement, specify an 80 mm bore, 475 mm stroke, PT ports, SUS420J2 rod material, a magnet for CMSE/DMSE sensors, and the 30 mm adjuster.
Keep in mind the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For dead-load holding, consider an AirTAC SAIL pneumatic lock or an external rod lock. Furthermore, with a 475 mm stroke, supporting the load with an external linear guide is critical to prevent excessive side loads on the rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX475-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder 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 adjusting screw acts as a mechanical stop that trims the effective stroke. For this 475 mm nominal stroke model, you can reduce the travel by up to 30 mm, resulting in a usable adjustable window of 445 to 475 mm.
