About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-10
The AirTAC SAIJ80X45-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated -10mm adjustment mechanism allows you to fine-tune the effective travel down to a 35mm minimum, establishing a precise 35-45mm usable window without requiring external stops.
This adjuster functions strictly as a mechanical end-stop to set the retract position, not as a locking mechanism, meaning it will not hold a load without live air pressure. For secure load-holding in fail-safe scenarios, consider the AirTAC SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed and DMSE solid-state 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 SAIJ80BX45-10 Is Used
Machine Commissioning
Dial in the exact 35-45mm travel end-position during initial setup without swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adapt the retract stroke by up to 10mm on automated lines when switching to a slightly different product size.
End-Stop Trimming
Use the rear adjuster screw to absorb mechanical tolerance and set a precise bottoming point for 80mm bore assembly tasks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-10 the Right Cylinder?
The adjustable stroke is highly beneficial during machine commissioning or product changeovers, allowing you to dial in the exact end-position within the 35-45mm range rather than machining custom spacers. Unlike a fixed-stroke SAI cylinder, this model offers on-the-fly travel tuning. When ordering, confirm the 80mm bore, 45mm stroke, 10mm adjustment, PT port thread, SUS304 stainless rod, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.
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 SAIJ80BX45-10 FAQ
At 0.9 MPa, the push force increases to 4523N. The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 45mm nominal stroke by up to 10mm, creating a 35-45mm usable travel window. It only sets the end-position and does not lock the load without live air pressure.
