About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75
The AirTAC SAIJ200X100-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25 to 100 mm, letting you dial back the nominal stroke by up to 75 mm during commissioning. Built to deliver massive thrust, it pushes 28274 N at 0.9 MPa, making it suitable for heavy-duty press operations.
This unit uses a SUS420J2 stainless steel rod for superior corrosion resistance and features a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without needing external stops. It is not a locking device; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75 Is Used
Heavy Pressing
Dial in the exact 25-100 mm travel window for heavy pressing and forming tasks that require precise end-position tuning during setup.
Line Changeover
Adjust the rear stopper quickly during product size changeovers on a manufacturing line without removing the cylinder or adding external stops.
Variable End Stops
Set custom retraction limits for automated heavy machinery, using the 75 mm adjustment range to adapt the stroke to varying material thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75 the Right Cylinder?
Choose this 200 mm bore when 0.5 MPa thrust (15708 N) is insufficient and you need the maximum 3204 kgf at 1.0 MPa. If your application requires less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers on a line, allowing variable end-stops without swapping the entire cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 100 mm stroke, 75 mm adjustment, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load risks are minimal, but the heavy M36x2 rod still handles high axial loads effectively.
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 SAIJ200AX100-75 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder generates a push force of 28274 N and a pull force of 15080 N. At 1.0 MPa, it reaches a maximum of 3204 kgf.
The rear adjuster screw lets you shorten the effective travel from the 100 mm nominal stroke down to 25 mm. This creates a 25-100 mm adjustable window, acting as a mechanical stop to fine-tune the retract position without replacing the cylinder.
