About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10S
The AirTAC SAIJ80X500-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 490 to 500 mm for precise end-position tuning. It delivers a robust 2513 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The barrel features an extruded aluminum profile with sensor grooves on both sides.
This specific SKU includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. The PT tapered port threads ensure a tight pneumatic seal, while the integrated rear stopper allows for on-the-fly machine setup adjustments without adding external stops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10S Is Used
Product Changeovers
Fine-tune the 490 to 500 mm travel end-stop during production line size changes without physically replacing the cylinder.
Machine Setup
Achieve exact end-position calibration at commissioning using the rear screw, avoiding the need to bolt on external mechanical stops.
Material Handling
Pushes heavy loads with 2513 N of force at 0.5 MPa while allowing minor stroke adjustments to accommodate varying package dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX500-10S the Right Cylinder?
Choose this 80 mm bore when an application requires more force than the 50 mm class (which provides 982 N push at 0.5 MPa) but does not need the full output of the 100 mm variant (3927 N at 0.5 MPa). The adjustable stroke is ideal for product changeovers, letting you dial in the exact 490 to 500 mm end position during commissioning rather than swapping out a fixed-stroke SAI cylinder.
Because this model features a 500 mm stroke, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading on the piston. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. For a direct ISO 15552 replacement match, specify an 80 mm bore, 500 mm stroke, 10 mm adjustment, PT ports, SUS420J2 rod, and a -S magnet.
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 SAIJ80AX500-10S 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 adjuster screw allows you to shorten the effective travel by up to 10 mm, creating a usable stroke window of 490 to 500 mm. This stopper only sets the travel end and does not lock the load without continuous air pressure.
