About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-40S
The AirTAC SAIJ80X150-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
This SKU provides a usable travel window of 110-150mm, letting you dial back the retract end-position by up to 40mm without adding external stops. It uses PT tapered G3/8 ports and includes variable air cushions at both ends to manage deceleration. The extruded aluminum barrel offers standard ISO 15552 mounting interchangeability.

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 SAIJ80AX150-40S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 110-150mm window during machine setup without physically replacing the cylinder.
Product Changeover
Quickly adapt the stroke on automated lines when product sizes change, using the 40mm rear adjustment screw to match new dimensions.
Material Positioning
Handle varying package lengths on a conveyor by adjusting the stopper position to push items accurately into staging areas.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-40S the Right Cylinder?
The 40mm adjustment range is ideal for product changeovers, allowing you to fine-tune the end stop at commissioning rather than swapping a fixed-stroke SAI cylinder. To replace this unit, match the 80mm bore, 150mm stroke, PT G3/8 port, and -S magnet.
The rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air pressure. For dead-drop protection, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ80AX150-40S FAQ
The rear adjuster screw lets you shorten the nominal 150mm stroke by up to 40mm, creating a usable travel window of 110-150mm. This allows fine-tuning of the end position during commissioning without external stops.
