About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-10
The AirTAC SAIJ80X65-10 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a 2513N push force at 0.5 MPa, making it well-suited for mid-weight industrial handling. The integrated rear stopper allows you to fine-tune the effective travel down from the 65mm nominal stroke to a precise 55-65mm window without adding external stops.
This unit features a SUS304 stainless steel piston rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts solely as a travel stop to dial in the end position; it does not hold the load if air pressure drops. For true load-holding without live air, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-10 Is Used
Machine Setup Tuning
Dial in the exact 55 to 65mm end-position during commissioning without swapping out the entire cylinder or adding external shims.
Product Changeover
Quickly adapt the retract stroke for different product sizes on a packaging line by turning the rear stopper screw.
Mid-Force Positioning
Leverage the 2513N push force at 0.5 MPa to move heavier fixtures precisely while retaining end-stop flexibility.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-10 the Right Cylinder?
Choose this 80mm bore when 50mm (982N at 0.5 MPa) is too weak but 100mm (3927N at 0.5 MPa) is unnecessarily large. The adjustable stroke is ideal for machine setup and product changeover, letting you dial in the 55-65mm travel window on the fly rather than machining custom spacers. Because the stroke is under 300mm, side-load stress on the 25mm rod is manageable, though external guides remain best practice for heavy lateral loads. To match this ISO 15552 replacement exactly, specify: 80mm bore, 65mm stroke, 10mm adjustment, PT G3/8 port, Basic/LB/TC mountings, and no magnet.

- ✓ 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 SAIJ80BX65-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 65mm nominal stroke by up to 10mm, creating a usable travel window of 55 to 65mm. It sets the end position but does not lock the load without live air pressure.
At 0.5 MPa it provides a push force of 2513N and a pull force of 2268N. At 0.7 MPa the push force increases to 3518N.
