About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-75S
The AirTAC SAIJ80X195-75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 120-195 mm, allowing you to dial back the 195 mm nominal stroke by up to 75 mm during commissioning. Operating at 0.5 MPa, it delivers 2513 N of pull force, while the PT tapered port threads ensure a leak-free pneumatic connection.
This unit includes a piston magnet for position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. The 25 mm SUS420J2 stainless steel rod offers high corrosion resistance and handles side loads well, though long unsupported travel still requires an external guide. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

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 SAIJ80AX195-75S Is Used
End-Position Tuning
Fine-tune the retract end position within the 120-195 mm window during machine commissioning without physically swapping cylinders.
Product Changeover
Quickly adapt the stroke length on packaging lines handling varying product sizes by dialing the rear stopper as needed.
Machining Clamps
Secure parts at a precisely defined travel limit, relying on the 2513 N pull force at 0.5 MPa to hold the workpiece during operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-75S the Right Cylinder?
Choose this adjustable-stroke model when your setup requires frequent product changeovers or exact end-position tuning without swapping the cylinder or adding external stops. If you need less force, stepping down to a 63 mm bore yields 1402 N of pull at 0.5 MPa; if your application requires more holding power, moving up to a 100 mm bore provides 3681 N of pull.
Because the stroke is 195 mm, an external guide is recommended to manage side loads. For load-holding without continuous air pressure, this cylinder is not a lock; you should select an SAIL air-released lock or BSAI clamp-lock cylinder instead. To match this ISO 15552 interchangeable unit, specify: 80 mm bore, 195 mm stroke, 75 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet.

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 SAIJ80AX195-75S FAQ
At 0.7 MPa, the pull force increases to 2268 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 195 mm nominal length, creating a usable travel window of 120-195 mm. It functions as a mechanical stop and does not lock the load without live air.
