About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40
The AirTAC SAIJ100X600-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. It features a carbon steel piston rod and a PT tapered port. By integrating an external stopper at the rear, this model allows you to fine-tune the effective travel down from the 600 mm nominal stroke to a minimum of 560 mm, creating a precise 560-600 mm adjustable window.
This adjuster acts purely as a mechanical stop to set the retract end position during commissioning or product changeover, eliminating the need to swap the cylinder or bolt on external stops. It is not a locking device and will not hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40 Is Used
Product Size Changeover
Dial in the 560-600 mm travel window during format changes to accommodate different package lengths without swapping out the entire actuator.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to perfect tooling alignment, avoiding the hassle of machining custom external spacers.
Long-Stroke Forming
Leverage the 7068N push force at 0.9 MPa for heavy pressing or forming tasks while retaining the flexibility to shorten the stroke by up to 40 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-40 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore falls short on power, as stepping down to SAIJ80X600-40 reduces thrust to 4523N at 0.9 MPa. The adjustable 560-600 mm travel window is ideal for lines running variable product sizes, letting you dial in the exact end-stop without changing hardware. Because the nominal stroke is 600 mm, the M20x1.5 rod will experience leverage forces under side loading; an external guide is recommended to prevent premature seal wear.
For a direct ISO 15552 replacement match, verify the 100 mm bore, 600 mm stroke, 40 mm adjustment range, PT port thread, and required mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR. If your process requires true load-holding without continuous air, consider the SAIL air-released lock or BSAI clamp-lock variants instead of relying on the rear stopper.
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 SAIJ100X600-40 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068N of push force and 3681N of pull force. It can achieve a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 600 mm nominal stroke by up to 40 mm. This creates a usable travel window of 560 to 600 mm for precise end-position tuning without replacing the cylinder.
