About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-20
The AirTAC SAIJ100X550-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 530-550 mm usable travel window, allowing you to dial back the 550 mm nominal stroke by up to 20 mm during commissioning.
This unit is configured with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses PT tapered port threads (G1/2) and relies on adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ100AX550-20 Is Used
Machine Setup Calibration
Fine-tune the 530-550 mm travel window during initial machine commissioning to achieve exact positioning without machining custom spacers.
Product Changeover Stops
Quickly adjust the retract end-stop by up to 20 mm to accommodate varying product lengths on a high-thrust conveyor line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-20 the Right Cylinder?
The adjustable rear stopper is ideal for product changeovers on a line, acting strictly as a travel stop rather than a position lock. Because the stroke is 550 mm, an external guide is strongly recommended to prevent excessive side-loading on the piston rod.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 550 mm stroke, 20 mm adjustment range, G1/2 PT port, and the required mounting style. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since no magnet is specified, position sensing requires adding a -S option to use AirTAC CMSE reed or DMSE electronic sensors.

- ✓ 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 SAIJ100AX550-20 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm from the 550 mm nominal length, creating a 530-550 mm usable travel window. This stopper only sets the travel end and does not hold the load without live air pressure.
