About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-75
The AirTAC SAIJ100X190-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 190 mm nominal travel to create a precise 115 to 190 mm usable window. This specific SKU features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and uses a PT tapered port thread.
Because the adjuster acts purely as a mechanical stop on the retract end, it cannot hold a load without live air pressure. For true load-holding, you would need a related SAIL or BSAI variant. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches if needed, though this non-magnet model requires an external track for reed or electronic sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX190-75 Is Used
Machine Changeover
Rapidly adapt the end position during product size transitions on a packaging line by dialing the rear stopper across the 115-190 mm window.
Pressing End-Tuning
Fine-tune the exact contact depth of a 5497 N pressing operation at commissioning without machining new external hard stops.
Variable End Stops
Use the wide 75 mm adjustment range to test multiple retraction distances on a heavy-duty fixture before locking in the final position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-75 the Right Cylinder?
Choose this 100 mm bore when your application demands high thrust—such as 5497 N at 0.7 MPa—that smaller 80 mm cylinders (delivering 3518 N at the same pressure) cannot provide. The 75 mm adjustment range is exceptionally wide, making this cylinder ideal for machines that undergo frequent product changeovers, as you can fine-tune the end position without swapping out the cylinder or adding external stops. If you need to hold a load mid-stroke without continuous air supply, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, since the SAIJ rear screw is only a travel stop.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 190 mm stroke, 75 mm adjustment, PT G1/2 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Although the 190 mm stroke is below the 300 mm side-load threshold, the 25 mm rod diameter provides robust resistance to minor deflection; for long unsupported loads, always use an external guide.

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 SAIJ100 Adjustable Cylinder SAIJ100AX190-75 FAQ
The rear adjusting screw acts as a mechanical stop that lets you trim the effective stroke back by up to 75 mm, creating a usable travel window of 115 to 190 mm. It only sets the retract end position and does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 5497 N.
