About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-100
The AirTAC SAIJ80X400-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 400 mm stroke that can be fine-tuned backward by up to 100 mm, yielding a highly flexible 300-400 mm usable travel window. Delivering a robust 4523 N of push force at 0.9 MPa, it is built to handle demanding actuation tasks.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G3/8) for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Because the rear screw acts purely as a mechanical stop, it cannot hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-100 Is Used
Variable End-Stop Positioning
Dial in precise 300-400 mm travel distances during machine commissioning to accommodate varying material thicknesses without mechanical rework.
Product Changeover Systems
Quickly adjust the stroke by up to 100 mm on packaging lines to handle different carton sizes or pallet depths on the fly.
Heavy-Duty Forming Press
Leverage the 4523 N push force at 0.9 MPa for pressing operations, using the rear stopper to fine-tune the bottoming position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-100 the Right Cylinder?
Select this 80 mm bore cylinder when your application requires substantial thrust—such as 3518 N at 0.7 MPa—but demands an adaptable end-of-travel position. The 100 mm adjustment range is ideal for machine changeovers, allowing you to dial in the exact 300-400 mm travel distance without swapping out the cylinder or adding external stops. If your setup requires less force, stepping down to a 63 mm bore yields 2805 N at 0.9 MPa.
Since this cylinder features a 400 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide rigidity, but you should still use an external guide rail to prevent side-loading damage over this extended travel. For load-holding without continuous air pressure, this standard SAIJ is insufficient; you would need an external rod lock or a pilot-operated check valve, or an AirTAC SAIL lock model. When replacing an ISO 15552 unit, match the 80 mm bore, 400 mm stroke, 100 mm adjuster, PT G3/8 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ80AX400-100 FAQ
At the maximum operating pressure of 0.9 MPa, this 80 mm bore cylinder generates 4523 N of push force and 4071 N of pull force. At 0.5 MPa, it provides 2513 N of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 400 mm down to 300 mm. This creates a 300-400 mm usable window for fine-tuning end positions during setup. The adjuster is a stop, not a lock, and cannot hold the load without live air pressure.
