About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-30
The AirTAC SAIJ100X50-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 20 to 50 mm usable travel window from its 50 mm nominal stroke. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning position sensing via CMSE or DMSE switches is not possible without adding an -S variant.
This unit utilizes a SUS420J2 stainless steel rod (material code A) paired with an M20x1.5 rod thread and a G1/2 port. The rear adjustment screw acts purely as a travel stop to decelerate the piston at the retract end; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series instead.

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 SAIJ100AX50-30 Is Used
Machine Changeover
Dial in the 20 to 50 mm stroke window during product size transitions to set precise retract positions without repositioning the cylinder body.
Variable End Stops
Adjust the retract position on the fly for flexible manufacturing lines, using the rear screw to trim up to 30 mm off the nominal stroke.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-30 the Right Cylinder?
The 30 mm adjustment range is perfect for commissioning fine-tune or product changeover, allowing you to dial in the exact end-stop without swapping cylinders or adding external stops. Because the stroke is under 300 mm, side-load concerns are minimal, though the robust 25 mm rod and M20x1.5 thread handle high forces well.
When matching an ISO 15552 replacement, verify the 100 mm bore, 50 mm stroke, 30 mm adjustment, PT tapered port thread, and the correct mounting choice from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.
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 SAIJ100AX50-30 FAQ
The rear adjuster screw lets you shorten the 50 mm nominal stroke, creating a 20 to 50 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without live air.
