About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-30
The AirTAC SAIJ32X260-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 230 to 260 mm, allowing you to dial back the 260 mm nominal stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits compact pneumatic setups requiring precise end-position tuning without adding external stops.
This SKU uses a SUS420J2 stainless steel rod for improved corrosion resistance and accepts PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific configuration omits the magnet, the grooves remain ready for standard mounting switches. The rear adjuster acts purely as a travel stop to fine-tune the retract position, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-30 Is Used
Machine Changeovers
Dial in the 230-260 mm travel window during product size transitions to set new retract endpoints without replacing the cylinder.
End-Stop Tuning
Use the rear adjusting screw to fine-tune the final retract position during commissioning, avoiding the need for external mechanical stops.
Indexing Conveyors
Adjust the stroke on the fly to accommodate varying package sizes or pusher distances along a material handling line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 345 N of pull force at 0.5 MPa and on-the-fly stroke trimming. The 30 mm adjustment range is ideal for product changeovers on a line, letting you reposition the end stop without swapping the entire cylinder. If your machine needs less force, stepping down is not an option in this footprint, but stepping up to a 40 mm bore yields 528 N of pull force. Conversely, if you need higher force, the 50 mm bore offers 825 N of pull force at the same pressure.
Because the 260 mm stroke is relatively long for a 32 mm bore, ensure your setup includes an external guide to handle side loads, as the 12 mm rod and M10x1.25 thread can only absorb limited lateral stress. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For true position holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This model supports the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

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 SAIJ32AX260-30 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 230 to 260 mm, which can be fine-tuned during commissioning without changing the cylinder's physical mounting.
At a 0.5 MPa operating pressure, the SAIJ32X260-30 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.
