About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-30
The AirTAC SAIJ100X290-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 260-290 mm, allowing you to dial back the nominal 290 mm stroke by up to 30 mm during commissioning.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, PT tapered port threads, and no internal magnet. The extruded aluminum barrel includes sensor grooves on both sides for future switch additions. The rear adjuster acts purely as a travel stop to set deceleration and end-position, not as a load-holding lock.

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 SAIJ100AX290-30 Is Used
Machine Changeover
Fine-tune the end position by up to 30 mm during product size changeovers without swapping the cylinder or reworking the machine frame.
Variable End Stops
Set precise retraction points for diverter arms or pushers handling different package lengths on a shared conveyor line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-30 the Right Cylinder?
The adjustable 260-290 mm window is ideal for product changeovers where the exact end-of-stroke position varies slightly by part size, eliminating the need to physically swap cylinders or bolt on external stops.
Because the 290 mm stroke is substantial, the 25 mm diameter rod and M20x1.5 rod thread provide a robust interface, but an external guide is recommended to manage side loads on long unsupported travel. If the machine requires the load to stay in place without live air pressure, note that this adjuster is only a stop; you should use an external rod lock or a related SAIL (air-released lock) cylinder. For ISO 15552 interchangeability, match the 100 mm bore, 290 mm stroke, 30 mm adjustment, PT G1/2 port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.
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 SAIJ100AX290-30 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from the 290 mm nominal stroke down to 260 mm. It acts as a mechanical stop to tune the end position at commissioning, but it does not lock or hold the load without live air pressure.
