About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100S
The AirTAC SAIJ63X290-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 290 mm stroke that can be dialed back by up to 100 mm, creating a highly flexible 190-290 mm usable travel window for precise end-position tuning during commissioning. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation tasks while featuring a PT tapered port and an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
This adjustable-stroke model integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors thanks to the built-in magnet (-S) housed within the dual-side sensor grooves of its extruded aluminum barrel. The rear adjuster functions strictly as a mechanical stop to set the travel end and relies on the integrated air cushions for deceleration; it does not hold the load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI variants.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100S Is Used
Product Changeover
Dial in the 190-290 mm travel window on the fly during format size changes on a packaging line, using the rear screw to set new end positions without replacing the cylinder.
Machine Setup
Fine-tune the retract stop during initial commissioning to achieve precise seating of components, leveraging the 100 mm adjustment range to perfect the end position.
Variable End Stops
Handle multiple product sizes on a single conveyor system by adjusting the stroke length as needed, relying on the 1559 N pull force to move loads efficiently.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-100S the Right Cylinder?
Choose this 63 mm bore cylinder when you need 1559 N pull force at 0.5 MPa with the ability to fine-tune the retract position across a 190-290 mm window without swapping cylinders or adding external stops. If your application requires less force, stepping down to a 50 mm bore yields 825 N pull force, while stepping up to an 80 mm bore provides 2268 N. Because this model features a 290 mm stroke, supporting the load with an external guide is recommended to prevent excessive side-loading on the SUS420J2 rod.
To match this exact configuration as an ISO 15552 replacement, specify the 63 mm bore, 290 mm stroke, 100 mm adjustment range, PT port threads, and the -S magnet option. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Operating speed ranges from 30-800 mm/s, making it highly versatile for dynamic machine setups.

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 SAIJ63AX290-100S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 290 mm down to 190 mm. It works alongside the air cushions to decelerate the load but does not lock or hold the position without continuous air pressure.
