About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-10
The AirTAC SAIJ100X425-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 415 to 425 mm, allowing you to dial back the nominal stroke by up to 10 mm during commissioning. The piston rod is built from SUS420J2 stainless steel for enhanced corrosion resistance.
This model uses a PT tapered G1/2 port and relies on variable air cushions at both ends to decelerate the load. The extruded aluminum barrel includes sensor grooves on both sides for easy switch placement. It is important to note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider a SAIL or BSAI variant.

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 SAIJ100AX425-10 Is Used
Machine Setup Tuning
Dial in the exact 415 to 425 mm retract position during initial machine commissioning without machining external stop blocks.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on packaging lines when transitioning between slightly different product sizes.
Conveyor Diverter
Fine-tune the diverting stroke on heavy material handling conveyors to accommodate varying package widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX425-10 the Right Cylinder?
Choose this adjustable SAIJ over a fixed SAI when you need fine end-position tuning without swapping cylinders or adding external stops. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. Because this 425 mm stroke exceeds 300 mm, an external guide is recommended to prevent excessive side-loading on the rod and thread. To replace an ISO 15552 cylinder, match the 100 mm bore, 425 mm stroke, 10 mm adjustment, PT G1/2 port, and the required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ100AX425-10 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 425 mm down to 415 mm. It only sets the end position and does not lock the load without live air pressure.
