About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-75
The AirTAC SAIJ80X375-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel. With a nominal 375 mm stroke and a 75 mm adjustment range, it provides a usable travel window of 300-375 mm. This bore delivers 2513 N of pull force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it robust enough for heavy positioning tasks.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. Remember that the rear adjuster functions strictly as a travel stop for end-position tuning, not a lock; it cannot hold a 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 SAIJ80BX375-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 300-375 mm window during machine commissioning to perfect product handling without machining new hard stops.
Product Size Changeovers
Quickly adapt automated lines to different package or part lengths by adjusting the rear screw, reducing downtime between production runs.
Heavy Assembly Positioning
Leverage the 2513 N pull force to move heavy jigs into place, using the adjustable stroke to fine-tune the final clamping location.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-75 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force—such as the 2513 N pull at 0.5 MPa—but demands on-the-fly end-position tuning without swapping cylinders or bolting on external stops. If your setup only needs 1402 N of pull force, step down to the 63 mm bore; if you require over 3681 N of pull, step up to the 100 mm bore. The adjustable stroke is ideal for machine changeovers where product sizes vary, letting you dial in the 300-375 mm travel window precisely.
Because the 375 mm stroke is relatively long, the 25 mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is still recommended to prevent excessive side-loading on the unsupported rod. For load-holding without continuous air pressure, this plain SAIJ cylinder is insufficient; you should look at the SAIL (air-released lock) or BSAI (clamp-lock) variants, or use an external pilot-operated check valve. This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

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 SAIJ80BX375-75 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from 375 mm down to 300 mm. It is a travel stop for tuning, not a lock, and the cylinder requires live air to hold position.
