About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75S
The AirTAC SAIJ200X95-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 20-95 mm. Built with an extruded aluminum barrel, it delivers massive thrust up to 15708 N at 0.5 MPa, making it suitable for heavy-duty pressing and clamping. The SUS420J2 stainless steel rod offers enhanced corrosion resistance compared to standard carbon steel.
This model includes a magnet (-S) for position sensing and uses PT tapered ports. The rear stopper allows precise end-position tuning during commissioning without adding external stops. Note that the adjuster acts only as a travel stop, not a load lock; for holding loads without live air, consider an external rod lock or the SAIL series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75S Is Used
Heavy-Duty Pressing
Delivers up to 15708 N of thrust at 0.5 MPa for forming and stamping operations requiring precise bottom-stop tuning.
Product Changeover
The 75 mm adjustment window allows operators to quickly adapt the stroke depth on a production line without swapping cylinders.
Automated Clamping
Ideal for securing large workpieces where the exact clamping position needs fine-tuning during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-75S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force, such as 21991 N push at 0.7 MPa, combined with variable end-stop positioning. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The adjustable 75 mm window is ideal for product changeovers, whereas a fixed SAI cylinder is better for static, unchanging strokes.
To match this ISO 15552 cylinder for replacement, specify: 200 mm bore, 95 mm stroke, 75 mm adjustment, PT G3/4 port, SUS420J2 rod (A), and a magnet (-S). Because the stroke is under 300 mm, side-load risks are moderate, but the 40 mm rod and M36x2 thread handle high axial loads effectively. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX95-75S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster allows you to shorten the 95 mm nominal stroke by up to 75 mm, providing an effective travel range of 20-95 mm. This stopper only sets the end position and does not lock the load without live air pressure.
