About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-10S
The AirTAC SAIJ80X65-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 65 mm stroke by up to 10 mm for a precise 55-65 mm usable travel window. This unit features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
It utilizes PT tapered port threads sized at G3/8 and relies on variable air cushions at both ends to decelerate the moving load. The rear adjuster functions strictly as a mechanical stop to set the travel end, not as a lock, meaning it will not hold a load without live air pressure. For operations requiring true load-holding without continuous pressure, consider the SAIL or BSAI series instead.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX65-10S Is Used
Machine Setup Calibration
Dial in the exact 55-65 mm travel window during commissioning to perfect end-position timing without adding external stops.
Product Changeover
Quickly adjust the retract end-position by up to 10 mm when switching between different product sizes on the same line.
Variable End-Stop Assembly
Fine-tune the stroke on automated assembly stations to accommodate minor variations in incoming part dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-10S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI cylinder when you need fine end-position tuning on the fly. The 25 mm piston rod and M20x1.5 thread provide robust side-load capacity, though any long unsupported stroke still requires an external guide.
When matching ISO 15552 interchangeable replacements, verify the 80 mm bore, 65 mm stroke, 10 mm adjustment range, PT G3/8 ports, and the -S magnet option. This cylinder uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR mounts.
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 SAIJ80BX65-10S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 65 mm nominal stroke by up to 10 mm, creating a 55-65 mm usable travel window. It is a travel stop and does not lock or hold the load without live air pressure.
