About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-50
The AirTAC SAIJ100X650-50 is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, allowing you to fine-tune the effective travel window anywhere between 600 and 650 mm during commissioning.
This specific SKU features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes dual-side sensor grooves, and while this variant omits the magnet, the housing remains fully compatible with CMSE reed and DMSE solid-state switches if a magnet is added later.

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 SAIJ100AX650-50 Is Used
Product Changeovers
Dial in a new end-stop position for varying package sizes on a packaging line using the 50 mm rear adjustment screw, avoiding the need to physically swap out the entire actuator.
Machine Setup Tuning
Fine-tune the 600-650 mm travel window during initial commissioning to perfectly time a heavy press operation, absorbing mechanical tolerances without adding external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-50 the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers on a packaging line, letting you dial in the exact end-stop without swapping the cylinder or adding external mechanical stops. For a fixed end-position without the adjustment feature, the standard SAI series is the direct alternative.
To replace an ISO 15552 cylinder with this model, match the 100 mm bore, 650 mm stroke, 50 mm adjustment range, PT port thread, and your required mounting accessory. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the stroke is 650 mm, the 25 mm rod and M20x1.5 thread require an external guide to prevent excessive side-loading on the unsupported piston. Finally, the rear adjuster acts only as a travel stop and cannot hold a load without live air; for fail-safe load holding, consider the SAIL or BSAI clamp-lock 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 SAIJ100AX650-50 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 650 mm down to 600 mm. It is a travel stop for fine-tuning end positions, not a lock, so it will not hold the load without continuous air pressure.
