About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-30S
The AirTAC SAIJ63X290-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 290mm travel that can be fine-tuned backward by up to 30mm, yielding a usable end-position window of 260-290mm. This specific configuration uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and incorporates a magnet for CMSE reed and DMSE electronic sensors.
Delivering 1559N of push force at 0.5MPa (2182N at 0.7MPa), it shares the standard SAI footprint but omits the FB, CA, CB, and CR mountings, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-30S Is Used
Machine Changeover
Dial in the retract distance by up to 30mm when switching between product sizes on a packaging line, eliminating the need to physically swap cylinders.
End-Position Tuning
Fine-tune the 260-290mm travel window during commissioning to perfectly time the mechanical stop without repositioning the entire ISO 15552 mount.
Corrosive Assembly Lines
Leverage the SUS420J2 stainless steel rod and 1559N thrust to push components reliably in environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-30S the Right Cylinder?
Choose this 63mm bore cylinder when an application requires 1559N of thrust at 0.5MPa and variable end-stops for product changeover. If your force requirements are lower, stepping down to a 50mm bore provides 982N, while moving up to an 80mm bore yields 2513N. Because the 290mm stroke exceeds 300mm threshold considerations, ensure an external guide supports the load to prevent excessive side-loading on the M16x1.5 rod thread.
This adjustable model is selected over a fixed-stroke SAI when you need to dial in the exact retract position without adding external stops or swapping cylinders. For applications requiring the load to be held mechanically without live air, this cylinder is insufficient; you should specify an AirTAC SAIL or BSAI series instead. To match this ISO 15552 replacement, specify: 63mm bore, 290mm stroke, 30mm adjustment, PT tapered ports, and the -S magnet option.

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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-30S FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 2182N.
The rear external screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 290mm down to 260mm. This creates a 260-290mm adjustable window for fine-tuning at commissioning, but it does not lock the load without continuous air pressure.
