About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10
The AirTAC SAIJ200X40-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. With a nominal 40 mm stroke and a 10 mm rear adjustment range, it provides a precise 30-40 mm usable travel window for dialing in exact end positions during commissioning without adding external stops. It features a robust 40 mm SUS420J2 stainless steel piston rod and PT tapered port threads.
This adjustable-stroke design allows operators to fine-tune the retract end-position on the fly, which is critical for high-force applications requiring strict positional accuracy. The rear adjuster acts purely as a mechanical stop to set the travel limit and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10 Is Used
Heavy Press Tuning
Dial in the exact 30-40 mm travel window during heavy press setup, ensuring precise material deformation without repositioning the entire cylinder.
Product Changeover
Quickly adjust the retract stop by up to 10 mm to accommodate slight variations in product thickness on a high-force assembly line.
Short-Stroke Clamping
Apply up to 15708N of clamping force at 0.5 MPa while fine-tuning the exact clamping position at the machine's commissioning stage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force combined with a short, highly adjustable stroke. If the full 10 mm adjustment window is unnecessary, stepping down to a 160 mm bore still provides 10053N push force at 0.5 MPa while reducing the physical envelope. The 40 mm SUS420J2 stainless rod offers excellent corrosion resistance and side-load capacity, though external guidance is recommended if lateral forces are present.
Because the nominal stroke is only 40 mm, the side-load risks typical of long unsupported strokes are minimized. This model uses a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Without a -S magnet, it does not support CMSE or DMSE 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 SAIJ200 Adjustable Cylinder SAIJ200AX40-10 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 40 mm nominal stroke cylinder, the 10 mm adjustment creates a usable 30-40 mm travel window, allowing precise end-position tuning without swapping the cylinder.
