About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-75S
The AirTAC SAIJ200X225-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708 N at 0.5 MPa. Its integrated 75 mm adjustment screw allows you to trim the effective travel down from the 225 mm nominal stroke, creating a 150-225 mm usable window. This fine-tuning capability is ideal for dialing in end positions during machine commissioning without swapping out the cylinder or adding external stops.
Built for demanding environments, this variant features a SUS420J2 stainless steel rod (option A) for heightened corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the included magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-75S Is Used
Heavy Press Tuning
Dial in the exact 150-225 mm end-position on a heavy press during commissioning to accommodate varying material thicknesses without external stops.
Product Changeover
Quickly adjust the retract distance up to 75 mm during product size changeovers on a packaging line to handle different package dimensions.
Large Assembly Jigs
Set precise variable end-stops for large-scale assembly jigs where the 15708 N thrust is needed to seat heavy components accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX225-75S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme push force, stepping up from a 160 mm cylinder that provides 10053 N at 0.5 MPa. The 75 mm rear adjuster acts purely as a travel stop to set the retract end-position; it does not hold the load without live air pressure. For genuine load-holding requirements, consider the SAIL pneumatic lock or BSAI clamp-lock series. Because the 225 mm stroke is substantial, always use an external guide to prevent side-loading damage to the rod.
This SAIJ200X225-75-S is dimensionally interchangeable per ISO 15552. To match this exact configuration, specify a 200 mm bore, 225 mm stroke, 75 mm adjustment range, PT tapered ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet option.

- ✓ 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 SAIJ200AX225-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push thrust and 15080 N of pull thrust. It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 225 mm nominal stroke by up to 75 mm, providing a 150-225 mm travel window. The adjuster is a mechanical stop that sets the end position; it is not a lock and will not hold the load without live air pressure.
