About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30
The AirTAC SAIJ80X600-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 600 mm stroke with a 30 mm external trim range, yielding a precise 570-600 mm usable travel window for fine-tuning end positions during commissioning. The 80 mm bore generates 4523 N of push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. It includes variable air cushions at both ends to manage kinetic energy. The rear adjuster acts solely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30 Is Used
Machine Setup & Changeover
Dial in the exact 570-600 mm retract position during line changeovers without fabricating new external hard stops.
Variable Product Routing
Adjust the stroke length on the fly to accommodate different package sizes moving through a sorting station.
Heavy-Duty Positioning
Leverage the 4523 N push force to move heavy pallets while fine-tuning the end-of-travel location during commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30 the Right Cylinder?
Choose this 80 mm bore actuator when your application requires 4523 N of thrust at 0.9 MPa and a variable end-stop. If you need less force, the 63 mm bore offers 2805 N; if you need more, the 100 mm bore provides 7068 N. The adjustable 570-600 mm travel window is ideal for product changeovers, allowing you to shorten the stroke by up to 30 mm without swapping the cylinder or adding external stops.
Because this is a 600 mm stroke, the 25 mm diameter rod and M20x1.5 thread will experience significant leverage forces if the load is unsupported; an external guide is strongly recommended to prevent side-load damage. This SAIJ model uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts. For any load-holding requirements without continuous air pressure, select a SAIL or BSAI series cylinder instead.
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 SAIJ80AX600-30 FAQ
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates 4523 N of push force and 4071 N of pull force.
A rear external screw acts as a mechanical stop, allowing you to shorten the effective travel from 600 mm down to 570 mm. This adjuster sets the end position but does not lock or hold the load without live air pressure.
