About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-50
The AirTAC SAIJ63X230-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 180 to 230 mm usable travel window. Delivering 1559 N of push force at 0.5 MPa, it integrates a G3/8 port and a 36 mm variable air cushion at both ends to decelerate the piston smoothly.
This SKU uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune end positions during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-50 Is Used
Product Changeover
Dial in the 180-230 mm travel window during packaging size transitions to set new end positions rapidly without changing the cylinder.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning using the rear stopper, avoiding the need for custom external shims.
Variable Forming Stops
Adjust the mechanical stop depth on the fly for assembly lines processing multiple part lengths within the 50 mm range.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-50 the Right Cylinder?
Choose this 63 mm bore when an application requires the 1559 N thrust at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N, or stepping down from an 80 mm bore yielding 2513 N. The 50 mm adjustment range is ideal for product changeovers, allowing operators to dial in the exact end-stop without swapping cylinders or adding external mechanical stops.
To match this ISO 15552 interchangeable cylinder, specify the 63 mm bore, 230 mm stroke, 50 mm adjustment, PT tapered port threads, and the SUS420J2 rod material. Because the 230 mm stroke exceeds 300 mm only marginally, side loads are minimal, but for long unsupported strokes, an external guide is still recommended. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ63AX230-50 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 can deliver up to 318 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 230 mm nominal stroke down to 180 mm. It only sets the end position and decelerates the load via the air cushion; it does not lock or hold the load without continuous air pressure.
