About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10S
The AirTAC SAIJ100X15-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning at commissioning without swapping components. It features a 100mm bore and a 15mm nominal stroke that can be dialed back by up to 10mm, yielding a highly versatile 5-15mm usable travel window for exacting clamping tasks. Delivering 3927N of push force at 0.5MPa, it provides substantial power in a compact footprint.
This variant is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and retains the standard extruded aluminum barrel with sensor grooves on both sides. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10S Is Used
Short-Stroke Clamping
Ideal for high-force clamping where the 5-15mm adjustable travel window allows operators to dial in the exact grip depth on varying workpiece thicknesses.
Machine Changeover
Enables rapid product-size changeovers on a line by adjusting the rear stopper to modify the end position without swapping the cylinder or adding external stops.
End-Stop Tuning
Perfect for automated assembly stations needing precise end-position tuning at commissioning to prevent crushing forces on delicate components.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10S the Right Cylinder?
Choose this 100mm bore cylinder when an application demands high force in a very short stroke, as stepping down to an 80mm bore would reduce the 0.5MPa push force to 2513N. The adjustable 5-15mm travel is ideal for product-size changeovers on a line, allowing operators to fine-tune the end stop without adding external spacers. For load-holding without continuous air pressure, this cylinder is insufficient; select an AirTAC SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, it directly matches standard mounting footprints. Ensure your setup specifies a 100mm bore, 15mm stroke, 10mm adjustment, PT port thread, and a magnet (-S). Because the stroke is under 300mm, side-load risks are minimal, but the robust 25mm rod and M20x1.5 thread handle high stress well.
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 SAIJ100 Adjustable Cylinder SAIJ100AX15-10S FAQ
At a 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop that shortens the 15mm nominal stroke by up to 10mm, creating a 5-15mm usable travel window. It sets the travel end and deceleration but does not lock or hold the load without live air pressure.
