About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75
The AirTAC SAIJ200X95-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708N of push force and 15080N of pull force at 0.5 MPa. By integrating a 75mm adjustment mechanism onto a 95mm nominal stroke, this unit provides a highly versatile 20-95mm usable travel window, enabling precise end-position tuning during commissioning without swapping hardware.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop for deceleration alongside the variable air cushions; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75 Is Used
Heavy Press Tuning
Dial in the exact 20-95mm travel window during heavy press commissioning to prevent over-travel without adding external mechanical stops.
Product Size Changeover
Quickly adapt clamping positions on a production line running varying large part sizes by adjusting the rear stopper up to 75mm.
High-Force Positioning
Leverage the 15708N push force at 0.5 MPa to move and position heavy industrial assemblies with fine-tuned end-stop accuracy.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75 the Right Cylinder?
Selecting this 200mm bore cylinder is ideal when an application demands extreme force combined with variable end-stops, such as accommodating product-size changes on a line. If the full 95mm stroke is unnecessary, stepping down to a 160mm bore yields 10053N push force at 0.5 MPa, which may suffice for lighter loads. Because the 95mm stroke is relatively short for this bore, side-loading is manageable, but the robust 40mm rod and M36x2 thread handle substantial offset stresses. For load-holding without continuous air pressure, an external pilot-operated check valve or a related SAIL lock cylinder is required, as the SAIJ adjuster is not a locking device. To match this ISO 15552 interchangeable cylinder, specify the 200mm bore, 95mm stroke, 75mm adjustment, PT G3/4 port, and mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ200AX95-75 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 a mechanical stop that allows you to trim the effective travel back from the 95mm nominal stroke. This creates a usable 20-95mm travel window for fine-tuning end positions at commissioning without replacing the cylinder.
