About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-40S
The AirTAC SAIJ80X190-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -40 mm adjustment mechanism allows you to fine-tune the effective travel, creating a usable stroke window between 150 and 190 mm without changing the physical cylinder length.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for electronic or reed sensing. The extruded aluminum barrel provides standard sensor grooves on both sides, and the rear adjuster functions purely as a travel stop for end-position tuning rather than a load-holding lock.

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 SAIJ80BX190-40S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 150 and 190 mm during machine commissioning to accommodate different material thicknesses without adding external stopper blocks.
Corrosive Assembly Stations
Utilize the SUS304 stainless steel rod in washdown or humid manufacturing environments where carbon steel rods would degrade, ensuring consistent cycling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-40S the Right Cylinder?
Select this 80 mm bore model when an application requires high force combined with variable end-stop positioning, such as accommodating product size changes on a conveyor. The SAIJ80X190-40-S is dimensionally interchangeable with ISO 15552 cylinders, utilizing a PT G3/8 port and supporting mounting options limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 190 mm stroke is below the 300 mm threshold, side-load stress is moderate, though the 25 mm rod and M20x1.5 thread handle typical loads well. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state switches. Remember that the rear adjuster only sets the retract position; for true load holding without live air, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80BX190-40S FAQ
The rear adjuster acts as a mechanical stop that shortens the nominal 190 mm stroke by up to 40 mm, giving you an adjustable travel window of 150 to 190 mm. It is a travel stop only, not a lock, meaning the cylinder requires live air to hold its position.
At the maximum operating pressure of 1.0 MPa, the push force reaches 513 kgf.
