About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-40S
The AirTAC SAIJ80X600-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial in the exact end-of-travel position during commissioning. It provides a usable travel window of 560 to 600 mm, trimming up to 40 mm off the nominal stroke without needing external stops. In the 80 mm bore class, it delivers robust thrust, pushing with 4523N and pulling with 2268N at 0.9 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is designed to work seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to set deceleration, meaning it will not hold a load safely without live air pressure.

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 SAIJ80BX600-40S Is Used
Machine Changeover Setup
Dial in the 560-600 mm travel window during product size changeovers, adjusting the rear stopper to hit new exact end positions without replacing the cylinder.
Variable End-Stop Positioning
Fine-tune the retract end-position on a long-stroke conveyor sorting gate, using the 40 mm adjustment to compensate for mechanical wear over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-40S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a packaging line, letting operators fine-tune the 560-600 mm travel window on the fly rather than swapping out a fixed-stroke SAI cylinder. For any load-holding requirements during an air-loss event, this cylinder cannot lock in place; you would need to specify a SAIL or BSAI series instead. Because the 600 mm stroke is long and the 25 mm rod with M20x1.5 thread can only handle so much lateral stress, an external guide rail is strongly recommended to prevent side-load damage. To match this ISO 15552 interchangeable cylinder, use a PT tapered port, the Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and a -S 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 SAIJ80BX600-40S FAQ
It can deliver a maximum push force of 513 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 600 mm nominal stroke by up to 40 mm, creating a 560-600 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
