About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-10S
The AirTAC SAIJ80X500-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 500 mm stroke that can be fine-tuned backward by up to 10 mm, yielding a usable travel window of 490-500 mm. The extruded aluminum barrel includes sensor grooves on both sides, and this version includes a magnet for position detection.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. Speeds range from 30-800 mm/s, supported by variable air cushions at both ends. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure. For position holding without continuous air, an external rod lock or the SAIL series is required.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-10S Is Used
Machine Changeover
Fine-tune the 490-500 mm end position during product size transitions without physically replacing the cylinder or adding external stopper blocks.
Corrosive Assembly
The SUS304 stainless steel rod and 80 mm bore provide reliable actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-10S the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than the 50 mm bore (982 N at 0.5 MPa) but less than the massive 100 mm bore (3927 N at 0.5 MPa). An adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact end position without swapping cylinders or adding external stops. Match the ISO 15552 replacement by confirming the 80 mm bore, 500 mm stroke, 10 mm adjustment, PT ports, and the -S magnet.
Because the stroke is 500 mm, the 25 mm rod diameter and M20x1.5 rod thread must manage significant side loads. Even with a robust rod, an external guide is recommended for long unsupported strokes to prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets found on other variants.

- ✓ 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 SAIJ80BX500-10S FAQ
The rear adjuster is a mechanical stopper that lets you shorten the effective stroke by up to 10 mm, creating a 490-500 mm travel window. It sets the end position but does not lock or hold the load without live air pressure.
At 0.7 MPa, the push force increases to 3518 N.
