About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-100S
The AirTAC SAIJ63X230-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. It provides a nominal 230 mm stroke that can be dialed back by up to 100 mm, yielding a highly versatile 130 to 230 mm usable travel window. This wide adjustment range is ideal for product changeovers on automated lines, eliminating the need to physically swap cylinders when end-position requirements shift. Delivering 2182 N of push force at 0.7 MPa, it handles robust actuation tasks with ease.
Equipped with a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The piston rod is manufactured from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and air connections use PT tapered threads (G3/8). The SAIJ mounting set omits FB, CA, CB, and CR brackets, utilizing a focused subset of ISO 15552 mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-100S Is Used
Machine Changeover
Dial in the exact end-stop for different product lengths during line changeovers without swapping out the actuator or adding external stop blocks.
End-Position Tuning
Fine-tune the retract stroke within the 130-230 mm window during commissioning to perfect seating forces and prevent mechanical crashing.
Variable Forming Stops
Adjust the travel distance on the fly for pneumatic pressing or forming stations that handle multiple material thicknesses or part profiles.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-100S the Right Cylinder?
Select this 63 mm bore cylinder when an application demands 1559 N of pull force at 0.5 MPa, bridging the gap between the 50 mm bore (825 N pull) and the larger 80 mm bore (2268 N pull). Choose the SAIJ adjustable-stroke variant over a fixed SAI model when commissioning requires fine end-position tuning or when accommodating multiple product sizes on a single machine. The rear adjuster acts purely as a mechanical travel stop and does not lock the load; for fail-safe load holding without live air pressure, specify an SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
Because the 230 mm stroke exceeds 300 mm only marginally, standard mounting is generally acceptable, but for any further extension or high-transverse-load applications, an external guide is strongly recommended to prevent rod binding. To match this exact configuration for an ISO 15552 replacement, specify: 63 mm bore, 230 mm nominal stroke, 100 mm adjustment range, PT G3/8 ports, SUS420J2 rod material, a magnet for CMSE/DMSE sensors, and a compatible mounting bracket from the SAIJ subset.

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 SAIJ63AX230-100S FAQ
At a standard 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 318 kgf.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its 230 mm nominal length down to 130 mm. This creates a 130-230 mm adjustable travel window for fine-tuning at commissioning, though it does not hold the load without live air pressure.
