About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-75
The AirTAC SAIJ200X175-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering immense thrust up to 3204 kgf at 1.0 MPa. By turning the integrated stopper screw, you can trim the nominal 175 mm stroke back by up to 75 mm, creating a precise 100-175 mm usable travel window for heavy-duty positioning tasks.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads for a robust pneumatic connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic switches if a magnet is specified later, ensuring seamless integration into large-scale machinery.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-75 Is Used
Heavy Press Tuning
Dial in the exact 100-175 mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Automated Line Changeover
Rapidly adjust the retract end-stop on packaging or palletizing machinery when switching to a different product size, minimizing downtime.
Large Fixture Positioning
Set precise retraction limits for massive welding or clamping fixtures, leveraging the 3204 kgf force capacity safely and accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-75 the Right Cylinder?
Choose this 200 mm bore when maximum push force is required, stepping down from the 3204 kgf peak to a 160 mm bore yields 2050 kgf if payload decreases. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end-position during commissioning or product changeover without adding external stops. The rear adjuster acts solely as a travel stop and does not hold the load without live air; for true position holding, consider an AirTAC SAIL or BSAI cylinder.
To match this exact unit for an ISO 15552 replacement, specify: 200 mm bore, 175 mm stroke, 75 mm adjustment range, PT tapered ports, SUS420J2 rod, and no magnet. Although the 175 mm stroke is under the 300 mm side-load threshold, the massive 40 mm rod diameter and M36x2 thread provide excellent structural rigidity, though external guides are still recommended for heavy offset loads.
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 SAIJ200AX175-75 FAQ
At 1.0 MPa, this 200 mm bore cylinder generates a maximum push force of 3204 kgf and a pull force of 15080 N. At a standard 0.5 MPa, it provides 15708 N of push force.
The rear adjuster screw acts as a mechanical stop that can trim the nominal 175 mm stroke back by up to 75 mm, providing an adjustable usable travel window between 100 and 175 mm. It only sets the end-position and does not lock the load without continuous air pressure.
