About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100
The AirTAC SAIJ63X240-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5MPa. It features an extruded aluminum barrel with sensor grooves on both sides and a SUS420J2 stainless steel rod. With a 240mm nominal stroke and a 100mm adjustment range, you can dial the effective travel back to anywhere within a 140-240mm window.
This wide adjustment span is ideal for product changeovers, allowing you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The rear screw acts purely as a travel stop to set the end position and relies on the integrated air cushion for deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100 Is Used
Product Size Changeovers
Leverage the 140-240mm travel window to quickly adapt machinery for different product lengths without physically swapping pneumatic components.
Commissioning End-Stop Tuning
Use the rear adjuster to precisely set the retract end position during initial machine setup, avoiding the need for external mechanical stops.
Variable Positioning Stops
Ideal for automated lines requiring flexible retract distances, utilizing the 100mm trim range to accommodate multiple operational modes.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX240-100 the Right Cylinder?
Choose this 63mm bore when you need significantly more thrust than a 50mm bore (982N push at 0.5MPa) but want to avoid the larger footprint and 2513N output of an 80mm option. The 100mm adjustment range is exceptionally useful for machines processing varying product sizes, providing a variable end-stop instead of committing to a fixed-stroke SAI cylinder. For load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 63mm bore, 240mm stroke, 100mm adjustment, PT tapered ports, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 240mm, ensure adequate external guiding to prevent excessive side-loading on the rod, despite the robust M16x1.5 rod thread.
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 SAIJ63AX240-100 FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
The rear adjuster allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 140-240mm from the 240mm nominal stroke, letting you fine-tune the end position without changing the cylinder.
