About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-20
The AirTAC SAIJ100X475-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 475 mm nominal travel by up to 20 mm. This creates a 455-475 mm usable stroke window, perfect for fine-tuning the retract end position during commissioning without swapping out the entire actuator. It delivers substantial thrust, pushing with 5497 N at 0.7 MPa and pulling with 3681 N.
This unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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.

Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-20 the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, letting you set a variable end-stop without adding external stops. To match this ISO 15552 replacement exactly, specify the 475 mm stroke, 20 mm adjustment, G1/2 PT port, SUS420J2 rod, and no magnet.
Because the 475 mm stroke is relatively long, the 25 mm rod diameter requires external guiding to prevent excessive side-loading on the seals. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ cannot hold a load without live air, so consider a SAIL or BSAI cylinder if load-holding is required.
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 SAIJ100AX475-20 FAQ
The rear adjusting screw acts as a mechanical stop that trims the retract stroke. For this SAIJ100X475-20, you can reduce the 475 mm nominal stroke by up to 20 mm, giving an effective travel window of 455 to 475 mm. It is a stop, not a lock, and does not hold the load without air pressure.
