About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-10
The AirTAC SAIJ80X275-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 265 to 275 mm, allowing you to dial back the nominal 275 mm stroke by up to 10 mm during machine commissioning.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop to fine-tune end positions without requiring external stops.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX275-10 Is Used
Machine Setup Tuning
Dial in the exact 265 to 275 mm end-position during initial commissioning to perfect a pressing operation without machining external spacers.
Product Changeover
Quickly adjust the stroke stop by up to 10 mm when a packaging line switches to a slightly different carton size, minimizing downtime.
Assembly Line Stops
Use the rear stopper to set a precise retraction point for an 80 mm bore actuator managing heavy 2513 N loads on a conveyor assembly line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-10 the Right Cylinder?
If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. Because the stroke is 275 mm, ensure an external guide supports the load to prevent excessive side loading on the rod.
To match this ISO 15552 interchangeable cylinder exactly, verify the 80 mm bore, 275 mm nominal stroke, 10 mm adjustment range, PT G3/8 ports, and the SUS304 rod material. Note that the plain SAIJ does not hold loads without live air; for pilot-operated locking, consider the SAIL or BSAI series.
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 SAIJ80BX275-10 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm, creating a 265 to 275 mm usable window. It acts as a mechanical stop to fine-tune the end position without changing the cylinder itself.
At 0.7 MPa, the push force increases to 3518 N.
