About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-40
The AirTAC SAIJ63X290-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 1559N pull force at 0.5 MPa and features a 250-290mm usable travel window, letting you dial back the nominal 290mm stroke by up to 40mm. This built-in adjustment allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
The 63mm bore uses a G3/8 port and a 20mm piston rod with an M16x1.5 thread. This model is configured with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The rear adjuster acts purely as a mechanical stop to set the travel end and deceleration point; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-40 Is Used
End-Position Tuning
Fine-tune the retract distance within the 250-290mm window during commissioning to perfectly align stops without machining external spacers.
Product Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when handling different product sizes, minimizing machine downtime.
Adjustable Clamping
Apply the 1559N pull force to secure parts of varying widths, using the rear screw to set the exact clamping depth.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-40 the Right Cylinder?
Choose this 63mm bore when you need higher thrust than a 50mm bore (982N push at 0.5 MPa) but want to avoid the larger footprint and 2513N pull force of an 80mm bore. The adjustable stroke is ideal for machine setups requiring a variable end-stop or product changeover, offering more flexibility than a fixed-stroke SAI cylinder. Because the total stroke is 290mm, an external guide is recommended to prevent excessive side-loading on the rod.
When matching an ISO 15552 replacement, specify the 63mm bore, 290mm stroke, 40mm adjustment range, PT tapered port thread, and your required mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. This configuration does not include a magnet for sensors.

- ✓ 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 SAIJ63AX290-40 FAQ
It features a rear adjusting screw that mechanically limits the retract stroke. You can trim the effective travel back by up to 40mm, creating a 250-290mm usable window to fine-tune the end position without changing the cylinder.
At 0.5 MPa operating pressure, the 63mm bore provides a push (extend) force of 1559N and a pull (retract) force of 1402N. The maximum force at 1.0 MPa is 318 kgf.
