About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-100
The AirTAC SAIJ80X260-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 160-260 mm usable travel window, allowing you to dial back the 260 mm nominal stroke by up to 100 mm during commissioning.
This specific configuration uses a SUS304 stainless steel piston rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ80BX260-100 Is Used
Machine Changeover
Quickly dial the stroke back from 260 mm to 160 mm when switching the production line to a shorter product format.
End-Position Tuning
Fine-tune the retract end-stop during commissioning without swapping out the entire cylinder or adding spacers.
Variable End Stops
Handle multiple actuation distances on a single fixture by adjusting the rear stopper within the 100 mm range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-100 the Right Cylinder?
Select this 80 mm bore adjustable cylinder when a fixed-stroke SAI cannot accommodate product changeovers without adding external physical stops. The rear adjuster acts purely as a travel stop for end-position tuning; it does not hold the load without live air pressure. For fail-safe load holding, consider an SAIL or BSAI cylinder instead. Since the 260 mm stroke exceeds 300 mm? No, but long unsupported strokes still require an external guide to prevent side-load damage to the 25 mm rod.
For an ISO 15552 replacement match, verify the 80 mm bore, 260 mm stroke, 100 mm adjustment range, PT tapered port thread, and the SUS304 rod material. Because no magnet is specified, position sensing requires adding a magnet or external detection. The 30-800 mm/s speed range matches standard pneumatic setups.
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 SAIJ80BX260-100 FAQ
At 0.9 MPa, the push force increases to 4523 N.
A rear screw stopper lets you shorten the effective stroke by up to 100 mm, creating a 160-260 mm travel window. It acts as a physical stop and does not lock the load without air pressure.
