About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-30S
The AirTAC SAIJ32X125-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 95 to 125 mm usable travel window, allowing you to dial back the 125 mm nominal stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance.
This adjustable model omits the FB, CA, CB, and CR mounts, offering a focused set of interfaces: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet enables precise tracking via CMSE reed or DMSE electronic sensors fitted into the dual-side barrel grooves. The PT tapered port ensures a tight, sealed pneumatic connection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-30S Is Used
Product Changeover
Quickly adjust the end-stop from 95 to 125 mm to accommodate varying package sizes on a packaging line without swapping hardware.
Machine Setup
Fine-tune the retract position during initial commissioning to align sensors and tooling perfectly, eliminating mechanical guesswork.
Variable End Stops
Set precise travel limits for light-duty pressing or positioning tasks where hitting a specific 95-125 mm window is critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-30S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and on-the-fly end-position tuning without adding external stops. If your process requires less force, stepping down is not an option in this series, but if you need higher force, the 40 mm bore provides 628 N. The rear adjuster acts purely as a mechanical stop for deceleration and positioning; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
This dimensionally interchangeable ISO 15552 cylinder uses a PT port and features a 12 mm rod with an M10x1.25 thread. Because the stroke is 125 mm, side-load risks are minimal, but always ensure the rod thread properly handles any lateral forces. It provides a drop-in replacement for standard ISO 15552 cylinders while adding crucial adjustability.

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 SAIJ32BX125-30S FAQ
The rear adjuster screw lets you shorten the effective travel from the 125 mm nominal stroke down to 95 mm, providing a 30 mm tuning window. It acts as a physical stop to set the end position and does not lock the load without continuous air pressure.
At a 0.5 MPa operating pressure, the SAIJ32X125-30-S generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
