About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-40
The AirTAC SAIJ80X260-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 220 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 40 mm during commissioning.
Equipped with a SUS304 stainless steel rod, this variant maximizes corrosion resistance for harsh environments. It uses a PT G3/8 port and reaches speeds of 30-800 mm/s. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR 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 SAIJ80BX260-40 Is Used
Variable End-Stop Tuning
Dial in the exact 220 to 260 mm travel window during machine setup to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Quickly reposition the retract end-point on packaging lines when switching to a different product size, minimizing downtime between runs.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod to push heavy jigs or doors in washdown areas where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-40 the Right Cylinder?
Choose this 80 mm bore when an application requires higher force than the 63 mm class, which yields 2182 N at 0.7 MPa. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping cylinders or adding external stops. Because the 260 mm stroke exceeds 300 mm is false here, but for longer unsupported strokes, an external guide is recommended to manage side load.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air. For fail-safe load holding, select a SAIL or BSAI cylinder instead. This model is dimensionally interchangeable per ISO 15552, featuring a PT G3/8 port and no magnet.
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 SAIJ80BX260-40 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the effective stroke from 260 mm down to 220 mm. This mechanical stopper fine-tunes the end position at commissioning but does not lock the load without live air pressure.
