About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10S
The AirTAC SAIJ63X105-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 1559N push force at 0.5MPa and features a 95-105mm usable travel window, letting you dial back the 105mm nominal stroke by up to 10mm during commissioning.
This variant includes a -S magnet for CMSE reed and DMSE electronic sensors, an SUS420J2 stainless steel rod, and PT tapered ports. The extruded aluminum barrel provides dual sensor grooves, while the rear stopper sets the end position without acting as a load lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10S Is Used
Product Changeover
Dial in the 95-105mm travel window to accommodate minor size variations between product batches without swapping hardware.
Machine Setup
Use the rear stopper to precisely set the retract end-position during initial commissioning, avoiding external shims.
End-Stop Trimming
Fine-tune the final position of tooling by trimming up to 10mm of stroke directly at the cylinder's rear adjuster.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-10S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982N push at 0.5MPa) lacks power or a 80mm bore (2513N) is excessive. The 10mm adjuster is ideal for fine-tuning end-of-stroke positions on product changeovers without external stops. For strokes over 300mm, use an external guide to manage side loads. The adjuster only halts travel; it does not hold loads without live air. For dead-end holding, use SAIL or BSAI cylinders. This model is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ63AX105-10S FAQ
At 0.5MPa it provides 1559N push and 1402N pull. At 0.7MPa the push force increases to 2182N.
The rear adjuster acts as a travel stop, allowing you to shorten the 105mm stroke by up to 10mm, creating a 95-105mm usable travel window. It is not a lock and requires live air to hold position.
