About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-100
The AirTAC SAIJ80X375-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 275 to 375 mm, allowing you to dial back the nominal 375 mm stroke by up to 100 mm during commissioning.
This 80 mm bore unit uses a robust 25 mm rod and M20x1.5 rod thread, which helps manage side loads on long strokes, though an external guide is still recommended for unsupported travel. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, position sensing requires external switches rather than embedded CMSE or DMSE electronic or reed sensors.

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 SAIJ80BX375-100 Is Used
Machine Changeover
Dial in the 275 to 375 mm travel window during product size transitions without replacing the cylinder or adding external mechanical stops.
Commissioning Tuning
Fine-tune the exact end-of-stroke position at startup using the rear adjuster screw to perfectly time the machine cycle.
Variable End Stops
Set precise retraction points on a conveyor sorting line, accommodating different package lengths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-100 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping hardware.
Because the 375 mm stroke is relatively long, ensure an external guide supports the load to prevent rod bending. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series instead. To match this ISO 15552 footprint exactly, specify the 80 mm bore, 375 mm stroke, 100 mm adjustment, PT ports, and your required mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ80BX375-100 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 375 mm down to 275 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
