About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-10
The AirTAC SAIJ80X115-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. With a nominal 115 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 105 to 115 mm.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX115-10 Is Used
Machine Setup Calibration
Dial in the exact 105 to 115 mm end-stop during initial commissioning to perfectly align tooling without machining custom spacer blocks.
Product Changeover
Quickly adjust the retract position on a packaging line when switching between slightly different product sizes that require precise 80 mm bore thrust.
Variable End-Stop Positioning
Utilize the rear screw to trim the stroke by up to 10 mm on assembly lines where minor positional variations are needed between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-10 the Right Cylinder?
The 10 mm rear adjuster is ideal for dialing in exact end-stops during machine setup or product changeover without adding external physical stops. To replace this cylinder with an ISO 15552 equivalent, match the 80 mm bore, 115 mm stroke, 10 mm adjustment, PT port thread, and the chosen mounting hardware.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device. The cylinder cannot hold a load without continuous live air pressure. If your setup requires true load-holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve.
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 SAIJ80BX115-10 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 10 mm from the nominal 115 mm stroke, creating a 105 to 115 mm usable window. It only sets the end position and does not lock the load without live air.
