About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-50
The AirTAC SAIJ100X550-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This allows you to fine-tune the retract end position precisely during commissioning without swapping out the entire actuator.
Built with a SUS420J2 stainless steel rod (code A) for enhanced durability against moisture, it uses a PT tapered G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air pressure is required to hold the load.

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 SAIJ100AX550-50 Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 500-550mm window during product size changeovers without physically replacing the cylinder.
Variable End-Stop Positioning
Fine-tune the stopping point of a diverter or pusher on a conveyor line to accommodate packages of varying lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-50 the Right Cylinder?
The 50mm adjustable window is ideal for product changeovers on a packaging line where the exact end-of-stroke position varies slightly by part size, saving you from adding external mechanical stops. Because the nominal stroke is 550mm, an external guide is recommended to manage side-load forces on the extended rod.
For a direct ISO 15552 replacement, match the 100mm bore, 550mm nominal stroke, 50mm adjustment, PT G1/2 port, and SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your machine requires true load-holding without continuous air pressure, select an AirTAC SAIL or BSAI cylinder instead of relying on this 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 SAIJ100AX550-50 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjusting screw lets you shorten the 550mm nominal stroke by up to 50mm, providing a usable travel window of 500 to 550mm. This stopper sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
