About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75
The AirTAC SAIJ200X75-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering immense thrust up to 15708N at 0.5 MPa. It features a SUS420J2 stainless steel rod and a 0-75mm adjustable travel window, allowing you to dial back the nominal 75mm stroke entirely to zero if needed. This makes it exceptionally versatile for high-force applications requiring exact end-position tuning during commissioning.
Instead of swapping the cylinder or adding external stops, the rear adjustment screw lets you fine-tune the retract end on the fly. The extruded aluminum barrel includes sensor grooves on both sides, and the unit omits FB, CA, CB, and CR mounts, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces for secure installation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75 Is Used
Heavy Press Tuning
Dial in the exact 0-75mm end-position on high-force pressing operations without changing out the entire cylinder setup.
Product Changeover
Quickly adjust the travel window during heavy machinery line changeovers to accommodate different product sizes.
Assembly Calibration
Fine-tune the retract stop during machine commissioning to guarantee precise alignment for massive components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75 the Right Cylinder?
Choose this 200mm bore model when your application demands extreme force, offering 15708N push and 15080N pull at 0.5 MPa. If your setup requires slightly less thrust, stepping down to a 160mm bore provides 10053N of push force. The 0-75mm adjustable window is ideal for product changeovers on heavy machinery, functioning as a variable end-stop rather than a fixed-travel SAI cylinder.
Because the stroke is 75mm, side-load concerns are minimal, but always ensure the M36x2 rod thread is properly supported. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552. Configuration: PT tapered ports, no magnet, SUS420J2 rod.
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 SAIJ200AX75-75 FAQ
At 0.5 MPa, it 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 screw lets you shorten the effective travel anywhere from the full 75mm down to 0mm. It acts as a mechanical stop to fine-tune the end position, but it does not lock or hold the load without continuous air pressure.
