About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-100
The AirTAC SAIJ63X200-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a 1402 Newton pull force at 0.5 MPa and utilizes a G3/8 port. Equipped with an SUS420J2 stainless steel rod, it provides excellent resistance to moisture while maintaining high structural rigidity.
This specific SKU provides a generous 100 to 200 mm usable travel window, allowing you to dial back the nominal 200 mm stroke by up to 100 mm. The external stopper enables highly precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It features variable air cushions at both ends and extruded aluminum barrel sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-100 Is Used
Product Changeovers
Dial in the exact retraction distance from 100 to 200 mm during machine setup to handle varying product lengths without physically swapping the actuator.
End-Position Tuning
Fine-tune the final end-of-stroke position during commissioning to compensate for mechanical tolerances, ensuring precise clamping without external stopper blocks.
Variable End Stops
Ideal for automated lines where the effective clamping depth must be adjusted on the fly, using the rear screw to safely limit the 200 mm nominal stroke.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-100 the Right Cylinder?
Choose this 63 mm bore adjustable-stroke cylinder when your application requires a wide travel window or frequent product-size changeovers on a line. If you need less force, stepping down to a 50 mm bore yields a 825 Newton pull at 0.5 MPa, whereas stepping up to an 80 mm bore provides 2268 Newtons. The SAIJ63X200-100 is dimensionally interchangeable per ISO 15552 and configured with PT tapered ports, a Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and no magnet.
The rear adjuster acts purely as a travel stop to set the retraction endpoint, not as a lock. It cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL series with an air-released lock or the BSAI clamp-lock variant. Since the nominal stroke is 200 mm, standard side-load guidance is still recommended for optimal rod bearing life.

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 SAIJ63AX200-100 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 100 mm. This creates a 100 to 200 mm usable travel window for precise end-position tuning without changing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ63X200-100 provides a push force of 1559 Newtons and a pull force of 1402 Newtons. At the maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
