About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-20S
The AirTAC SAIJ32X75-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 75mm stroke with a 20mm adjustment range, creating a usable travel window of 55-75mm for precise end-position tuning during commissioning. Delivering 402N of push force at 0.5MPa, it is engineered with a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread.
This adjustable-stop design allows you to dial in the exact retract distance without swapping the cylinder or adding external stops, though the adjuster acts only as a travel stop and does not hold the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-20S Is Used
Machine Changeover
Dial in the 55-75mm travel window during product size transitions on a packaging line without swapping out the entire cylinder assembly.
End-Stop Calibration
Fine-tune the retract end position at commissioning using the rear adjuster screw to perfect a delicate 402N pressing operation.
Variable Diverter
Adjust the stroke on the fly for a conveyor sorting arm, ensuring accurate routing of varying package dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-20S the Right Cylinder?
Choose this 32mm bore when an application requires 402N of push force at 0.5MPa; stepping up to a 40mm bore yields 628N, while dropping to a smaller bore would sacrifice too much thrust. The adjustable 55-75mm travel window is ideal for product changeovers on a conveyor or fine-tuning a machine setup without machining new hard stops. When matching an ISO 15552 replacement, verify the 75mm stroke, 20mm adjustment, PT port thread, SUS304 (B) rod material, and the -S magnet requirement.
Although the 32mm bore carries a robust M10x1.25 rod thread, long unsupported strokes always require an external guide to prevent side-load damage. For applications that must hold a load without continuous air pressure, this cylinder is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32BX75-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20mm. This creates a usable travel window of 55-75mm, allowing precise end-position tuning without replacing the cylinder.
At 0.5MPa operating pressure, it provides 402N of push force and 345N of pull force. The maximum thrust is 82kgf at 1.0MPa.
