About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-50S
The AirTAC SAIJ80X150-50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves.
This model provides a 100-150mm adjustable travel window, allowing you to trim the nominal 150mm stroke by up to 50mm during commissioning. The rear screw functions purely as an end-position stop for fine-tuning product changeovers, not as a load-holding lock. It features PT tapered port threads and variable air cushions at both ends to manage deceleration.

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 SAIJ80BX150-50S Is Used
Product Changeovers
Dial in the 100-150mm travel window on the fly to accommodate varying package sizes without replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning using the rear adjuster, ensuring precise alignment of high-force tooling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-50S the Right Cylinder?
The adjustable 100-150mm travel window is ideal for machinery requiring flexible end-stops without swapping hardware.
For direct compatibility, match the 80mm bore, 150mm nominal stroke, 50mm adjustment range, PT G3/8 port, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster cannot hold loads without live air; for true position holding, consider an external rod lock or the AirTAC SAIL series.
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 SAIJ80BX150-50S FAQ
The rear adjuster allows you to shorten the effective travel from the 150mm nominal stroke down to 100mm. It acts as a mechanical stop to set the exact end position, but it is not a lock and will not hold the load without continuous air pressure.
