About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10S
The AirTAC SAIJ80X50-10-S is a double-acting, single-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. In this bore size, it delivers a robust 4523N of push force at 0.9 MPa, making it well-suited for high-thrust tasks.
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.

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.
High-Force Positioning
Leverage the 4523N push force at 0.9 MPa to move heavy pallets or fixtures while precisely setting the end-of-stroke location.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10S the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires more force than the 63 mm size (which provides 2805N push at 0.9 MPa) but does not necessitate stepping up to the massive 7068N output of a 100 mm bore. 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
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder provides 4523N of push force and 4071N of pull force. 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.
