Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-10S
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-10S
The AirTAC SAIJ80X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 790 to 800 mm. Delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, it handles heavy actuation tasks while allowing precise end-position tuning during commissioning. The integrated magnet supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves.
This model features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a travel stop to fine-tune the retract position without adding external physical stops. It is not a locking device; the cylinder relies on live air pressure to hold its load, so for true fail-safe load holding, consider SAIL or BSAI variants instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-10S Is Used
Long-Stroke Machine Setup
Dial in the exact 790-800 mm retract end-stop during initial commissioning of large equipment without installing secondary external physical stops.
Product Size Changeover
Quickly adapt the stroke length on a packaging line when product dimensions change, using the rear screw to fine-tune the retraction point.
Heavy Material Handling
Leverage the 2513 N push force at 0.5 MPa to move heavy pallets or workpieces over an 800 mm travel distance with precision.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX800-10S the Right Cylinder?
Selecting this 80 mm bore cylinder over a smaller 63 mm bore (which yields 1559 N push at 0.5 MPa) is ideal when your application requires higher thrust and a long 800 mm travel. The 10 mm rear adjustment screw lets you dial in the exact retract end-stop during machine setup or product changeover without physically swapping the cylinder. To replace an ISO 15552 cylinder, match the 80 mm bore, 800 mm stroke, 10 mm adjustment, PT G3/8 ports, and the -S magnet requirement.
Because the 800 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 rod thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported piston rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.
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 SAIJ80BX800-10S FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 4523 N.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 10 mm, creating a 790 to 800 mm usable travel window. It fine-tunes the retract end position but does not lock the load without live air pressure.
