About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10S
The AirTAC SAIJ32X280-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 280 mm stroke that can be dialed back by up to 10 mm, giving you a precise 270-280 mm usable travel window for fine end-position tuning during commissioning. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod (option B) for superior corrosion resistance. The -S option includes a magnet for position sensing with CMSE reed and DMSE electronic switches.
This model uses a G1/8 port and M10x1.25 rod thread. Because the adjuster acts purely as a mechanical stop on the retract end, it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. The extruded aluminum barrel includes sensor grooves on both sides, and mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10S Is Used
Machine Setup & Changeover
Fine-tune the 270-280 mm travel end-stop during product line changeovers without physically replacing the cylinder or bolting on external stopper blocks.
Variable End-Stop Positioning
Dial in the exact retract distance within the 10 mm adjustment window to accommodate minor variations in component placement on automated assembly lines.
Light-Duty Clamping
Utilize the 402 N push force for securing light components during machining, using the rear screw to precisely set the clamping depth and prevent over-travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-10S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa and you need the flexibility to trim the travel back by 10 mm without swapping out the cylinder or adding external stops. If your setup needs more thrust, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. Conversely, if you require a fixed stroke without the rear adjuster, the standard SAI series is a simpler alternative.
Because the 280 mm stroke is relatively long for this compact 32 mm bore, the M10x1.25 rod is more susceptible to side-loading and deflection under heavy off-center loads. For strokes of 300 mm or more, or when handling high lateral forces, always use an external guide rail to prevent premature seal wear and rod bending. This cylinder is dimensionally interchangeable per ISO 15552 standards, featuring a PT tapered port thread.

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 SAIJ32BX280-10S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear external adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10 mm. This creates a 270-280 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
