About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20
The AirTAC SAIJ100X110-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 110 mm nominal stroke by up to 20 mm. This yields a precise 90-110 mm usable travel window, enabling fine end-position tuning at commissioning without swapping out the physical cylinder or adding external stops. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear screw acts as a travel stop to set deceleration, it does not hold the load without live air; for dead-load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20 Is Used
Machine Changeover
Dial in the 90-110 mm travel window during product size changes to set new extended positions without physically remounting the actuator.
End-Stop Calibration
Fine-tune the final extended position during commissioning using the rear adjuster, preventing hard mechanical crashes on heavy tooling.
Heavy Forming Press
Leverage the 3927 N push force at 0.5 MPa for pressing or holding heavy components, relying on the rear stop to set the exact depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust—such as 3927 N push at 0.5 MPa—combined with variable end-stops for product changeovers. If your setup needs less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable stroke is ideal for machine setup where the exact extended position needs micro-tuning on the fly, unlike a fixed-stroke SAI cylinder.
Because the 110 mm stroke is relatively short, side-loading is less of a concern than with longer strokes, but the 25 mm rod and M20x1.5 thread still handle robust loads. To match this ISO 15552 interchangeable cylinder exactly, specify the 100 mm bore, 110 mm stroke, 20 mm adjustment, PT port, and the SUS420J2 rod material. Note that the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 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 SAIJ100 Adjustable Cylinder SAIJ100AX110-20 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm. This provides a usable travel window of 90 to 110 mm, allowing you to trim the end position without replacing the cylinder.
At a 0.5 MPa operating pressure, it provides a push force of 3927 N and a pull force of 3681 N. If higher pressure is used, the push force increases to 5497 N at 0.7 MPa.
