About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-40S
The AirTAC SAIJ80X105-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 105 mm travel by up to 40 mm. This creates a flexible 65 to 105 mm usable stroke window, allowing precise end-position tuning during commissioning without swapping out the physical unit. Delivering 2513 N of pull force at 0.5 MPa, it handles substantial actuation tasks with ease.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB and CR options to streamline your setup.

| 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 SAIJ80BX105-40S Is Used
Product Changeovers
Dial in the 65-105 mm travel window on the fly to accommodate varying package sizes without physically replacing the cylinder.
Commissioning Calibration
Fine-tune the exact end-of-stroke position during machine setup to prevent crushing delicate components.
Variable End Stops
Use the rear mechanical stopper to establish safe, repeatable retraction points in automated assembly lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-40S the Right Cylinder?
Choose this 80 mm bore if your application requires the 2513 N pull force at 0.5 MPa; stepping down to a 63 mm bore drops that to 1402 N, while a 100 mm bore increases it to 3681 N. An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for frequent product size changeovers on a packaging line. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider an SAIL or BSAI cylinder.
To match this ISO 15552 replacement exactly, specify: 80 mm bore, 105 mm stroke, 40 mm adjustment, PT tapered port, the reduced SAIJ mounting set, and the -S magnet. Because the 25 mm rod and M20x1.5 thread handle high side loads, ensure proper external guiding if the load is heavy or off-center.
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 SAIJ80BX105-40S FAQ
The rear adjuster screw lets you shorten the 105 mm nominal stroke by up to 40 mm, providing a usable travel window of 65 to 105 mm. This allows precise end-position tuning without adding external stops.
