About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-20S
The AirTAC SAIJ200X500-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive 15708N push force at 0.5 MPa. Its 500mm nominal stroke can be dialed back by up to 20mm, creating a precise 480-500mm usable travel window for heavy-duty commissioning. A SUS420J2 stainless steel rod (code A) provides excellent corrosion resistance, while the built-in magnet (-S) supports position sensing.
Unlike fixed-stroke actuators, this model allows fine end-position tuning at machine setup without swapping the cylinder or adding external stops. The 40mm rod and M36x2 thread provide exceptional rigidity for high side-load capacity, and the extruded aluminum barrel features dual sensor grooves compatible with CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-20S Is Used
Heavy Press Tuning
Dial in the exact 480-500mm end-stop during heavy press commissioning to accommodate material thickness variations without remounting the actuator.
Product Line Changeover
Quickly adjust the retract position on automated assembly lines when switching between large product sizes, saving hours of mechanical retooling.
Large Material Handling
Leverage the 15708N push force to move heavy workpieces, using the fine stroke adjustment to perfectly seat parts against rigid backstops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-20S the Right Cylinder?
Choose this 200mm bore actuator when an application demands extreme thrust, such as 15708N push or 15080N pull at 0.5 MPa. If you need less force, stepping down to a 160mm bore yields 10053N push, but this 200mm size is unmatched for heavy loads. The adjustable 480-500mm window is ideal for product changeovers, allowing you to trim the retract end-position on the fly rather than machining new hard stops.
Because the 500mm stroke is substantial, always use an external guide to support the load and prevent excessive side-loading on the rod. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold the load without live air. For true load-holding without pneumatic pressure, select an AirTAC SAIL or BSAI cylinder instead. This PT-ported, ISO 15552 interchangeable actuator uses mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX500-20S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster acts as an external stopper that trims the effective stroke back by up to 20mm, providing a usable travel window of 480-500mm. It sets the end position but does not lock the load without continuous air pressure.
