About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50S
The AirTAC SAIJ100X900-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 900mm travel that can be fine-tuned down by up to 50mm, yielding a usable end-position window of 850-900mm. This allows precise positioning during commissioning without adding external stops.
This variant includes a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads for a robust pneumatic connection. The extruded aluminum barrel integrates sensor grooves on both sides, and the included magnet supports position detection via CMSE reed or DMSE electronic solid-state switches. 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.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50S Is Used
Variable End-Stop Positioning
Dial in the exact 850-900mm retraction point during machine setup to accommodate varying product lengths without changing cylinders.
Product Changeover Adjustment
Quickly reconfigure the stroke end-position on packaging lines when switching to a different package size, using the rear 50mm screw mechanism.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50S the Right Cylinder?
The 50mm adjustment range is ideal for product changeovers on a line, letting you dial in the exact end-stop without swapping the cylinder. For any load-holding requirements without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; consider an AirTAC SAIL or BSAI cylinder instead.
With a 900mm stroke, the 25mm rod is highly susceptible to side-loading and sagging. An external linear guide is strongly recommended to prevent premature seal wear and binding. To replace this unit with another ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 50mm adjustment, PT G1/2 port, and the -S magnet requirement.
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 SAIJ100AX900-50S FAQ
At 0.5MPa operating pressure, the push force is 3927N and the pull force is 3681N. At 0.9MPa, the push force increases to 7068N.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from 900mm down to 850mm. This adjuster only sets the travel end and does not lock or hold the load without live air pressure.
