About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX15-10
The AirTAC SAIJ63X15-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod and PT tapered port threads. The integrated rear screw allows you to fine-tune the end position at commissioning without adding external stops.
With a 15mm nominal stroke and a 10mm adjustment code, this model provides a usable travel window of 5-15mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. This adjustable stopper sets the retract position precisely but does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX15-10 Is Used
Precision End-Stop Tuning
Dial in the exact 5 to 15mm retract position during machine commissioning to achieve perfect seating without machining custom spacers.
Product Size Changeover
Quickly adapt a clamping station to new part dimensions by turning the rear adjuster, shifting the effective stroke within its 10mm window.
Short-Stroke Clamping
Utilize the 1559N push force at 0.5 MPa for secure, short-travel clamping tasks where a standard fixed cylinder lacks positioning flexibility.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX15-10 the Right Cylinder?
Choose this 63mm bore cylinder when an application requires exact short-stroke positioning, as it supplies 1559N push and 1402N pull at 0.5 MPa. If your setup needs less force, stepping down to a 50mm bore yields 982N push, whereas an 80mm bore provides 2513N push for heavier loads. The adjustable travel is ideal for machine changeovers where the end-stop varies slightly.
To match this ISO 15552 dimensionally interchangeable cylinder, specify the 63mm bore, 15mm stroke, 10mm adjustment, G3/8 or PT port, and your preferred mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. For load-holding without continuous air pressure, consider an external rod lock or the AirTAC SAIL series instead of relying on the adjuster.
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 SAIJ63AX15-10 FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
The rear adjuster acts as a stopper that lets you trim the effective travel back by up to 10mm. For this 15mm stroke cylinder, it creates a usable travel window of 5 to 15mm, allowing precise end-position tuning without swapping the cylinder.
