About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30S
The AirTAC SAIJ32X350-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 350 mm stroke that can be fine-tuned down by up to 30 mm, creating a precise 320-350 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and features a built-in magnet for position sensing.
This adjustable-stroke design allows you to dial in the retract end-position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop, not a lock, meaning it cannot hold a load without live air pressure. For load-holding requirements, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30S Is Used
Machine Setup Changeover
Fine-tune the 320-350 mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Dial in the exact retract position on automated tooling, using the rear adjuster to compensate for mechanical tolerances at commissioning.
Light-Load Sorting
Provide 402 N of push force at 0.5 MPa for diverting small parts on a conveyor, with the SUS304 rod offering corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with the flexibility to trim the stroke by up to 30 mm during machine setup or product changeover. If your application requires less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N of push force. The PT tapered port and G1/8 connection are standard for this bore size.
Because this model features a 350 mm stroke, the 12 mm rod should be adequately supported by an external guide to prevent excessive side-loading and premature seal wear. When specifying a replacement, ensure you match the ISO 15552 dimensions, the 350 mm stroke, the 30 mm adjustment range, the PT port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ32BX350-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 320 to 350 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
