About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30S
The AirTAC SAIJ32X325-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 295-325 mm usable travel window, letting you trim the nominal 325 mm stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks. The barrel is extruded aluminum with sensor grooves on both sides.
This SKU includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. It uses PT tapered port threads (G1/8). The rear adjuster acts purely as a travel stop to set deceleration and end-position; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30S Is Used
Product Changeover Stops
Dial in the 295-325 mm travel window to accommodate different part lengths on a machining line without physically swapping the actuator.
Commissioning Fine-Tuning
Trim up to 30 mm of stroke at setup to perfect the exact end-of-travel position and prevent mechanical crashes.
Light-Duty Diverter
Use the 402 N push force at 0.5 MPa to move small packages on a conveyor, adjusting the stroke as lane widths vary.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops. If your process needs less force, drop down a size; if you need more power, stepping up to a 40 mm bore yields 628 N push at 0.5 MPa. Because the stroke is 325 mm on a 12 mm rod, long unsupported travel invites deflection, so an external guide is recommended to prevent side-load wear.
Select the adjustable SAIJ over a fixed SAI when facing product changeovers or variable end-stops on a line. For load-holding without continuous air pressure, the rear stop is insufficient, so you would need a SAIL pilot-lock or BSAI clamp-lock cylinder instead. To match this ISO 15552 interchangeable unit, specify: 32 bore, 325 stroke, 30 adjust, PT port, SUS420J2 rod, and -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 Adjustable Cylinder SAIJ32 SAIJ32AX325-30S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
A rear screw stopper lets you shorten the 325 mm nominal stroke by up to 30 mm, creating a 295-325 mm travel window. It functions as an end-stop, not a lock, so it cannot hold the load without live air.
