About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-10S
It features a SUS304 stainless steel rod and a PT tapered port. The built-in adjustment screw allows you to trim the effective travel back by up to 10 mm, creating a precise 365-375 mm usable window for fine-tuning end positions during commissioning.
Because the nominal stroke is 375 mm, the 25 mm rod and M20x1.5 thread must handle increased leverage, meaning an external guide is recommended to prevent excessive side-loading. The extruded aluminum barrel includes sensor grooves on both sides, and the included magnet (-S) supports CMSE reed and DMSE electronic solid-state switches for exact position detection.

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 SAIJ80BX375-10S Is Used
Product Changeover
Quickly dial in the 365-375 mm end position during packaging line format changes without replacing the cylinder or adding external mechanical stops.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise alignment, utilizing the 10 mm adjustment range to perfect the tooling stroke.
Variable End Stops
Ideal for automated assembly equipment needing a customizable retract distance, letting operators trim the 375 mm stroke by up to 10 mm on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, allowing you to dial in the 365-375 mm travel window without adding external stops or swapping the cylinder for a fixed-stroke SAI.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 375 mm stroke, 10 mm adjustment, PT ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ80BX375-10S 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 shorten the 375 mm nominal stroke by up to 10 mm, providing a usable travel window of 365-375 mm. It only sets the travel end and does not lock the load without continuous air pressure.
