About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-10
The AirTAC SAIJ100X550-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the travel end-position at commissioning. With a 550 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 540-550 mm to perfectly dial in machine stops without adding external hardware. It delivers robust thrust, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock or hold the load without continuous 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 SAIJ100AX550-10 Is Used
Machine Setup Fine-Tuning
Dial in the exact 540-550 mm end-position during initial commissioning to achieve perfect alignment without machining custom spacers.
Product Size Changeover
Quickly adjust the travel end by up to 10 mm when running a different product size on the same line, minimizing downtime.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-10 the Right Cylinder?
Choose this 100 mm bore when you need substantial force—pushing 7068 N at 0.9 MPa—and precise 540-550 mm end-position control. If your application requires less force, stepping down to an 80 mm bore drops the push force to 4523 N at 0.9 MPa. The adjustable-stroke design is ideal for product changeovers where exact end-stops vary slightly, saving you from swapping out a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, verify the 100 mm bore, 550 mm stroke, 10 mm adjustment, PT port thread, and mounting set.
Because this model has a 550 mm stroke, the M20x1.5 rod and piston assembly can experience side-loading forces if the load is unsupported. Always use an external guide rail to prevent premature seal wear. For applications requiring the cylinder to hold its position without live air, note that this adjuster is not a lock—consider an AirTAC SAIL or BSAI series instead. The SAIJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100AX550-10 FAQ
The pull force is 3681 N at 0.5 MPa. It operates at a speed range of 30-800 mm/s.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 540-550 mm from the 550 mm nominal stroke. The adjuster acts as a mechanical stop to set the end position and is not a lock, meaning the cylinder will not hold the load without live air pressure.
