About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100
The AirTAC SAIJ200X325-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering 15708 N of push force at 0.5 MPa. It features a 325 mm nominal stroke paired with a 100 mm rear adjustment range, creating a usable travel window of 225 to 325 mm. This built-in adjuster allows operators to fine-tune the retract end position directly at commissioning without adding external stops.
Built with a SUS420J2 stainless steel rod and PT tapered ports, this extruded aluminum profile cylinder omits tie-rod construction. It supports speeds of 30-500 mm/s and includes variable air cushions at both ends to manage kinetic energy. The rear stopper sets the travel limit but does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100 Is Used
Heavy Machinery Setup
Dial in the exact retract position of large forming presses during initial commissioning using the 100 mm adjustment window.
Product Size Changeover
Quickly adapt automated lines to different large-format product sizes by adjusting the travel end from 325 mm down to 225 mm.
Variable End Stops
Replace hard external stops with the integrated rear screw to fine-tune the stroke limit on heavy 15708 N push applications.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-100 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires immense thrust, stepping up from a 160 mm bore that provides 10053 N at 0.5 MPa. The 100 mm adjustment range is ideal for product changeovers on large machinery, allowing the end-stop to be dialed back precisely without swapping the cylinder for a fixed-stroke SAI variant. Because the nominal stroke is 325 mm, an external guide is recommended to handle side loads and protect the 40 mm rod during extended travel.
To match this configuration for an ISO 15552 replacement, specify the 200 mm bore, 325 mm stroke, 100 mm adjustment, PT port thread, and SUS420J2 rod material. Note that a plain SAIJ does not hold position without live air; for load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ200AX325-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At a maximum 1.0 MPa, it achieves a top push force of 31979 N.
The rear adjuster acts as a mechanical stop that trims the effective stroke. For this model, the 325 mm nominal stroke can be dialed back by up to 100 mm, resulting in a usable travel window of 225 to 325 mm. It requires live air to function and does not lock the load.
