About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-30S
The AirTAC SAIJ80X375-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 345 to 375 mm usable travel window, allowing you to dial back the nominal 375 mm stroke by up to 30 mm during commissioning.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

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 SAIJ80BX375-30S Is Used
Product Changeover
Dial in the exact 345 to 375 mm end-stop during machine setup for different product lengths without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the rear screw stopper to perfect fixture alignment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-30S the Right Cylinder?
The adjustable 345-375 mm window is selected over a fixed SAI cylinder when a machine requires fine end-position tuning for product changeovers without swapping the physical actuator.
For an exact ISO 15552 replacement match, verify the 80 mm bore, 375 mm nominal stroke, 30 mm adjustment range, PT tapered port, and the -S magnet option. Because the stroke is 375 mm, the M20x1.5 rod thread and 25 mm rod diameter still require an external guide to prevent excessive side-loading on the unsupported piston. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live pressure, use an external rod lock or pilot-operated check valve, or select an SAIL or BSAI cylinder.
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 SAIJ80BX375-30S FAQ
The rear adjuster is a mechanical stop that lets you shorten the effective travel from 375 mm down to a minimum of 345 mm. This allows precise end-position tuning without adding external stops, though it does not lock or hold the load without live air pressure.
