About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-75
The AirTAC SAIJ80X275-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position during commissioning. With a nominal 275 mm stroke and a 75 mm adjustment range, it provides a usable travel window of 200-275 mm.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered ports (G3/8). Because the stroke extends to 275 mm, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the barrel seals. The extruded aluminum profile includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic switches if a magnet is added later.

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 SAIJ80BX275-75 Is Used
Product Changeover Dials
Quickly shift the retract travel between 200 and 275 mm via the rear screw when processing different part sizes on the same fixture.
Variable End-Stop Diverter
Sets the exact push-off distance for a heavy 80 mm diverter mechanism without needing to bolt on external stopper blocks.
Machine Setup Tuning
Dials in the precise end-position during initial commissioning to prevent overtravel damage, using the 2513 N pull force to cycle heavy gates.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-75 the Right Cylinder?
Select this 80 mm bore cylinder when a 50 mm bore falls short on thrust (offering only 825 N pull at 0.5 MPa) and you need the 2513 N retract force to move heavier jigs. The 75 mm adjustable stop is ideal for product changeovers on a line, letting you shift the end-position dynamically without swapping the cylinder or adding physical spacers. For any application requiring the load to be held in place without continuous live air pressure, remember that this rear adjuster acts only as a travel stop, not a lock; you should instead consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder.
This SAIJ80X275-75 is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets. To match this exact configuration when replacing an ISO 15552 cylinder, verify the 80 mm bore, 275 mm stroke, 75 mm adjustment, PT G3/8 port, SUS304 rod, and no magnet.

- ✓ 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 SAIJ80BX275-75 FAQ
The rear adjuster screw lets you shorten the effective retract stroke by up to 75 mm, creating a usable travel window of 200 to 275 mm. It acts as a mechanical stop to fine-tune the end position without swapping the cylinder.
At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
