About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10S
The AirTAC SAIJ80X50-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 40-50 mm by allowing you to dial back the 50 mm nominal stroke by up to 10 mm during commissioning.
This SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. It includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load 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 SAIJ80BX50-10S Is Used
Variable End-Stop Tooling
Fine-tune the 40-50 mm travel window on the fly to accommodate varying material thicknesses or tool lengths without physically swapping the cylinder.
Machine Changeover
Rapidly adjust the retract end-position by up to 10 mm during product size transitions on a packaging or handling line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring a variable end-stop or fine-tuning without adding external physical stops, unlike a fixed-stroke SAI cylinder. Because the stroke is 50 mm, external side-load guides are less critical, but the 25 mm rod and M20x1.5 thread handle side loads well. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or select an AirTAC SAIL or BSAI cylinder. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.
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 SAIJ80BX50-10S FAQ
It can deliver a maximum of 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 40-50 mm. This stopper decelerates the travel end for fine-tuning but does not lock or hold the load without live air pressure.
