About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX35-10S
The AirTAC SAIJ80X35-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 35mm nominal stroke by up to 10mm. This creates a precise 25-35mm usable travel window, perfect for fine-tuning end positions at commissioning without swapping out the unit.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and carries an -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a G3/8 port and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ80BX35-10S Is Used
End-Position Tuning
Dial in the exact retract distance within the 25-35mm window during machine commissioning without adding external stops.
Product Changeover
Quickly adapt the cylinder travel to accommodate slightly different product sizes on the same production line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX35-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring a variable end-stop, allowing you to trim the travel window to 25mm during product changeovers. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop; you would need an external rod lock, pilot-operated check valve, or an AirTAC SAIL or BSAI cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard replacements with its 80mm bore, 35mm stroke, 10mm adjustment, PT tapered port threads, and -S magnet. Operating speed ranges from 30 to 800mm/s. Because the stroke is under 300mm, the 25mm rod handles normal loads well, though long unsupported strokes would still require an external guide.
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 SAIJ80BX35-10S FAQ
At 0.9MPa, the push force increases to 4523N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 35mm nominal stroke by up to 10mm, creating a usable travel window of 25-35mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
