About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-50
The AirTAC SAIJ80X65-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 65mm stroke back by up to 50mm. This yields a highly versatile 15-65mm usable travel window, letting you fine-tune the retract end position precisely during commissioning without adding external stops.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads (G3/8). The 25mm rod diameter and M20x1.5 thread provide excellent rigidity, handling higher side loads than smaller bores. The rear adjuster acts purely as a mechanical stop to set the travel end, complementing the standard variable air cushions at both ends.

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 SAIJ80BX65-50 Is Used
Machine Changeover
Dial in the 15-65mm travel window during product size changes on a packaging line without swapping the entire cylinder.
End-Position Tuning
Fine-tune the retract stroke at commissioning to hit exact mechanical endpoints, avoiding the need to machine external spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-50 the Right Cylinder?
The 15-65mm adjustable window is perfect for product changeovers on a line where end-position tuning is frequently required. Because the stroke is under 300mm, side-load stress is manageable, though long unsupported loads still need an external guide. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold position without live air. For load-holding without pressure, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 80mm bore, 65mm stroke, 50mm adjustment, PT G3/8 ports, and SUS304 rod material.
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 SAIJ80BX65-50 FAQ
It can deliver up to 513 kgf at its maximum 1.0MPa pressure.
The rear adjuster screw allows you to shorten the 65mm nominal stroke by up to 50mm, creating a 15-65mm usable travel window. The adjuster acts as a mechanical stop to set the end position, but it is not a lock and requires live air to maintain force.
