About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX280-10S
The AirTAC SAIJ80X280-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a nominal 280 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 270 to 280 mm. This enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for AirTAC CMSE reed and DMSE electronic sensors. The piston rod uses SUS304 stainless steel for superior corrosion resistance, and the PT tapered port threads ensure a robust pneumatic connection.

| 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 SAIJ80BX280-10S Is Used
Machine Setup Tuning
Dial in the exact 270-280 mm end position during commissioning to perfect a pressing operation without machining custom spacers.
Product Size Changeover
Quickly adjust the retract stop on a conveyor sorter when switching between different package sizes on the same line.
Variable End-Stop Clamping
Fine-tune the clamping depth on a workholding fixture to accommodate varying material thicknesses on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX280-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers. Because the 280 mm stroke exceeds 300 mm is not met here, but with longer unsupported strokes, always use an external guide to manage side load, as even the 25 mm rod and M20x1.5 thread have limits.
The rear adjuster acts strictly as a travel stop, not a lock, meaning the cylinder will not hold a load without live air. For load-holding without pressure, consider the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX280-10S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This creates a 270 to 280 mm usable travel window, allowing you to fine-tune the retract position without adding external stops.
