About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-50S
The AirTAC SAIJ100X650-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel to anywhere within a 600 to 650 mm window. This makes it highly suitable for heavy-duty positioning tasks that require exact end-stop tuning without swapping out hardware.
This SKU features an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the unit relies on a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ100AX650-50S Is Used
Product Changeover
Dial in the 600-650 mm travel window during format size changes on a packaging line, avoiding the need to physically swap cylinders for different carton lengths.
Variable End-Stop Diverter
Set precise retract positions for a heavy diverter arm on a conveyor, tuning the stroke by up to 50 mm to accommodate varying product widths without reprogramming the PLC.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-50S the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm option steps the thrust up significantly from 2513 N to 3927 N at 0.5 MPa, which is critical if your fixture mass has grown. The 50 mm rear adjuster is chosen when a process requires variable end-stops for product changeovers, acting purely as a travel stop rather than a load-holding lock. If your application demands position holding without live air pressure, you must pivot to the SAIL or BSAI series, or employ an external pilot-operated check valve.
Because the 650 mm stroke is substantial, the 25 mm rod and M20x1.5 thread will endure higher bending moments, meaning an external guide rail is strongly recommended to prevent excessive side-loading. To achieve a true ISO 15552 replacement match, verify the 100 mm bore, 650 mm stroke, 50 mm adjustment, PT tapered port threads, the -S magnet, and your required mounting bracket from the available SAIJ subset.
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 SAIJ100AX650-50S FAQ
If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
The rear external adjuster acts as a mechanical stop, allowing you to shorten the 650 mm nominal stroke by up to 50 mm, creating a usable travel window of 600 to 650 mm. It only sets the end position and does not lock the load without live air pressure.
