About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-100
The AirTAC SAIJ100X210-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 110-210mm, letting you dial back the 210mm nominal stroke by up to 100mm during commissioning.
This unit uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks the internal magnet required for CMSE or DMSE switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-100 Is Used
Product Changeover
Dial the travel back from 210mm down to 110mm to accommodate different package sizes on the same conveyor line without swapping hardware.
Machine Setup
Fine-tune the exact end-of-stroke position during commissioning to perfect pressing or clamping depth on heavy assemblies.
Variable End Stops
Use the 100mm adjustment window to create multiple stopping points for a single actuator operating across diverse machining operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-100 the Right Cylinder?
Select this 100mm bore actuator when an application requires high thrust (up to 3927N at 0.5MPa) alongside flexible end-position tuning. The 100mm adjustment range here is ideal for product changeovers on a line, whereas a fixed SAI cylinder would require physical replacement to alter the end-stop.
For replacing an ISO 15552 cylinder, match the 100mm bore, 210mm stroke, PT tapered ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted. Because the stroke is 210mm, ensure adequate external guiding to prevent excessive side-load on the 25mm rod. For load-holding without live pressure, select a SAIL or BSAI 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 SAIJ100 Adjustable Cylinder SAIJ100AX210-100 FAQ
At 0.9MPa, the push force increases to 7068N.
The rear adjusting screw acts as a mechanical stopper, allowing you to trim the effective travel anywhere within a 110-210mm window. It only decelerates and sets the travel end; it does not lock or hold the load without continuous air pressure.
