About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10
The AirTAC SAIJ200X375-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708 N push force at 0.5 MPa. It features an extruded aluminum barrel with dual sensor grooves rather than a traditional tie-rod build. A rear mechanical stopper allows you to fine-tune the extend position, creating a precise 365-375 mm usable travel window from the 375 mm nominal stroke.
This model utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads with a G3/4 connection. The 40 mm rod diameter and M36x2 thread provide a robust interface capable of handling significant side loads, though an external guide is strongly recommended for this 375 mm stroke. Operating speed ranges from 30-500 mm/s, supported by 50 mm air cushions at both ends to manage kinetic energy.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10 Is Used
Heavy Press Tuning
Dial in the exact end-of-stroke position on high-tonnage pressing operations within the 365-375 mm window without changing the fixture.
Product Line Changeover
Quickly adjust the extend stop during automated line format changes to accommodate slightly different large-scale product dimensions.
Large Material Handling
Move heavy structural components or assemblies with up to 15708 N of push force while fine-tuning the resting position during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-10 the Right Cylinder?
Select this 200 mm bore cylinder when your application requires extreme thrust—up to 21991 N at 0.7 MPa—surpassing the 10053 N output of the neighboring 160 mm bore. The 10 mm adjustable range is ideal for final machine setup or minor product size changes, preventing the need to physically swap cylinders or bolt on external stops. If your process requires the load to be held securely without continuous live air pressure, note that this rear adjuster functions strictly as a travel stop, not a lock; you would need to integrate an AirTAC SAIL or BSAI series cylinder instead.
For an exact ISO 15552 replacement match, verify the 200 mm bore, 375 mm stroke, 10 mm adjustment range, PT port thread, and required mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this unit lacks the -S magnet suffix, it will not trigger position sensors directly; if electronic or reed switch feedback is needed, choose a model with the -S option to utilize AirTAC DMSE solid-state or CMSE reed switches.

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 SAIJ200AX375-10 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 365-375 mm. It only sets the end position and does not lock the load without live air pressure.
