About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100
The AirTAC SAIJ200X475-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 475mm nominal stroke that can be dialed back by up to 100mm, yielding a 375-475mm usable travel window. This massive bore generates 15708N of push force and 15080N of pull force at 0.5MPa, making it suitable for heavy-duty industrial positioning.
This specific configuration incorporates an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while no magnet is specified for this SKU, the design supports AirTAC CMSE reed and DMSE electronic sensors when position detection is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100 Is Used
Heavy Press Tuning
Dial in the exact end position for large metal stamping or pressing operations, using the 100mm adjustment window to compensate for material thickness variations.
Pallet Changeover
Quickly adapt a heavy-duty conveyor diverter arm to handle different pallet sizes without physically replacing the actuator or adding mechanical spacers.
Large Assembly Jigs
Provide adjustable end-stops for massive automotive or industrial component assembly jigs where the final closure distance requires precise field calibration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100 the Right Cylinder?
Choose this 200mm bore when a 160mm bore (providing 10053N push at 0.5MPa) is insufficient for your load. The 100mm adjustment range is highly advantageous on long-stroke machinery, allowing you to fine-tune the retract end position during commissioning or product changeover without swapping cylinders or adding external stops. Because the 475mm stroke is long, an external guide is recommended to manage side loads on the 40mm rod and M36x2 thread.
For a true ISO 15552 replacement, match the 200mm bore, 475mm stroke, 100mm adjustment, PT port threads, SUS420J2 rod, and no magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ200 Adjustable Cylinder SAIJ200AX475-100 FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. This means the 475mm nominal stroke can be fine-tuned down to a 375mm travel window to achieve the exact end position needed during machine setup.
