About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-30S
The AirTAC SAIJ100X900-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This yields an effective usable travel window of 870-900 mm, allowing you to dial in the exact end position at commissioning without swapping out the cylinder or adding external stops.
Built with a SUS420J2 stainless steel rod (option A) for enhanced durability, this model includes a magnet for CMSE reed and DMSE electronic sensors. It uses PT tapered ports (G1/2) and relies on the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

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 SAIJ100AX900-30S Is Used
Variable End-Stop Forming
Dial in the exact 870-900 mm travel window during press setup to accommodate different material thicknesses without changing the cylinder.
Product Changeover Diverters
Quickly adjust the rear stopper on a sorting line to handle varying package sizes on the fly, ensuring precise positioning.
Machine Setup Tuning
Fine-tune the final retract position at commissioning to align with downstream equipment, avoiding the need for custom machined spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-30S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires heavy thrust (up to 801 kgf at 1.0 MPa) and precise variable end-stops; if you need less force, stepping down to an 80 mm bore yields 4523N at 0.9 MPa. Because the 900 mm stroke is long and unsupported, the 25 mm rod diameter and M20x1.5 thread will not prevent rod sag, so an external guide is mandatory to handle side loads.
Choose this adjustable-stroke SAIJ over a fixed SAI when you need commissioning flexibility or frequent product-size changeovers. Remember that the rear adjuster only halts travel; it does not brake or hold the load. For true load-holding without continuous air pressure, integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable unit exactly, specify: 100 mm bore, 900 mm stroke, 30 mm adjustment, PT G1/2 port, desired mounting, and the -S magnet.

- ✓ 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 SAIJ100AX900-30S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf of push thrust.
The rear adjusting screw allows you to shorten the 900 mm nominal stroke by up to 30 mm, creating an adjustable travel window of 870-900 mm. This stopper sets the travel end and deceleration point but does not lock or hold the load without continuous air pressure.
