About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10
The AirTAC SAIJ200X20-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 15708N push force at 0.5 MPa, making it a heavy-duty choice for substantial loads. The integrated rear stopper allows you to trim the 20 mm nominal stroke back by up to 10 mm, creating a precise 10 to 20 mm usable travel window for exact positioning.
This model features a SUS420J2 stainless steel rod (option A) for enhanced resistance against corrosion and side-load wear, paired with a PT tapered port thread for a robust pneumatic connection. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches if position feedback is later required. Mounting options include the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10 Is Used
Heavy-Duty Press Fit Tuning
Dial in the exact bottoming position during stamping or press-fit operations. The 10 mm adjustment window lets operators compensate for tooling wear without changing the cylinder.
Machine Changeover Setup
Quickly adapt end positions when switching product sizes on a high-force assembly line. The rear stopper allows rapid 10 mm travel modifications to meet new part dimensions.
Short-Stroke Clamping
Secure massive workpieces with up to 15708N of force. The adjustable end-stop ensures the clamp seats perfectly against varying material thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10 the Right Cylinder?
Select this 200 mm bore actuator when you need maximum thrust in a compact footprint, delivering 15708N at just 0.5 MPa. The adjustable stroke is ideal for applications requiring variable end stops or fine-tuning during machine commissioning without swapping hardware. If your process needs to hold a load without continuous live air pressure, note that this rear adjuster acts only as a travel stop and not a lock; consider the AirTAC SAIL or BSAI clamp-lock series instead. To replace an ISO 15552 cylinder, match the 200 mm bore, 20 mm stroke, 10 mm adjustment, PT port, and desired mounting bracket.
Because the stroke is relatively short at 20 mm, the 40 mm rod diameter provides exceptional rigidity against side loads without requiring an external guide. The operating speed range for this bore is 30-500 mm/s.

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 SAIJ200AX20-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708N of push force and 15080N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 20 mm nominal stroke by up to 10 mm. This creates a usable travel window of 10 to 20 mm, enabling fine end-position tuning without replacing the cylinder or adding external stops.
