About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10
The AirTAC SAIJ80X950-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a robust 2513N push force at 0.5 MPa and features a 950mm nominal stroke that can be fine-tuned down by 10mm, yielding a 940-950mm usable travel window. This built-in adjuster allows precise end-position tuning during commissioning without adding external stops.
This specific configuration incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the M20x1.5 rod thread handles substantial side loads effectively across the long 950mm stroke.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10 Is Used
Machine Changeover
Dial in the 940-950mm travel window during product size changes without swapping out the entire actuator or repositioning hard stops.
Long-Stroke Positioning
Use the 2513N thrust to push heavy carriers along a 950mm path, making micro-adjustments to the rear stopper for final alignment.
Assembly Line Tuning
Fine-tune the end-of-stroke position during initial commissioning to perfectly seat parts, relying on the built-in 10mm adjustment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-10 the Right Cylinder?
Choose this 80mm bore cylinder when an application requires approximately 2513N of push force at 0.5 MPa, stepping up from a 63mm bore that offers 1559N, or down from a 100mm bore providing 3927N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering more flexibility than a fixed-stroke SAI cylinder. Because the nominal stroke is 950mm, an external guide is strongly recommended to prevent excessive side-loading on the rod.
When specifying an ISO 15552 replacement, match the 80mm bore, 950mm stroke, 10mm adjustment range, PT G3/8 port, and the desired mounting style. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR options. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX950-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw lets you shorten the 950mm nominal stroke by up to 10mm, creating a 940-950mm travel window. It functions purely as a mechanical stop to fine-tune the end position and does not lock the load.
