About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10
The AirTAC SAIJ80X500-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 490-500mm usable travel window, allowing you to dial back the nominal 500mm stroke by up to 10mm during commissioning. Delivering 2513N of push force at 0.5MPa, it handles heavy positioning tasks without needing external stops.
This SKU uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Remember that the rear adjuster acts strictly as a travel stop for end-position tuning, not a lock, so it cannot hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10 Is Used
Machine Setup & Changeover
Dial in the exact 490-500mm retract position during line changeovers without physically swapping cylinders or adding external mechanical stops.
Variable End-Stop Positioning
Fine-tune the end-of-stroke stopping point on a long-stroke conveyor diverter to accommodate varying package dimensions on the fly.
Heavy-Duty Assembly Tuning
Leverage the 2513N push force at 0.5MPa for robust pressing operations while using the 10mm adjuster to perfect the final clamp depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10 the Right Cylinder?
Select this adjustable model when your assembly requires fine-tuning of the retract end-position at setup or during product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. If your application needs less force, stepping down to a 63mm bore yields 1559N at 0.5MPa; if you require higher thrust, moving to a 100mm bore provides 3927N.
Because this cylinder has a 500mm stroke, the 25mm rod diameter should still be guided externally to prevent excessive side-loading and premature seal wear. For exact ISO 15552 replacement matching, verify the 80mm bore, 500mm stroke, 10mm adjustment range, PT port thread, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since no magnet is specified, position-sensing switches are not supported on this specific configuration.
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 SAIJ80AX500-10 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a 490-500mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a lock, meaning it cannot hold a load without continuous air pressure.
At 0.5MPa operating pressure, the SAIJ80X500-10 generates 2513N of push force and 2268N of pull force. It can reach up to 4523N of push force at 0.9MPa.
