About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-100
The AirTAC SAIJ200X350-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It provides a substantial 28274N of push force at 0.9 MPa, making it suited for heavy-duty positioning tasks. The barrel is extruded aluminum with sensor grooves on both sides, and the piston rod uses SUS420J2 stainless steel for enhanced corrosion resistance.
This specific SKU features a 350 mm nominal stroke paired with a 100 mm adjustment range, yielding a usable travel window of 250 to 350 mm. This built-in adjustability allows you to dial in the exact retract end-position during commissioning without swapping out the cylinder or adding external stops. It uses PT tapered port threads and operates at speeds between 30 and 500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-100 Is Used
Heavy Press Positioning
Dial in the exact bottoming position of a large press during setup. The 250-350 mm travel window lets you compensate for tooling wear without disassembling the line.
Pallet Size Changeover
Adjust the retract distance on the fly to accommodate different pallet lengths on a heavy-duty conveyor system, saving time during product transitions.
Large Assembly Stations
Fine-tune the end-stop for large component mating, ensuring delicate parts meet precisely without slamming, utilizing the rear adjustment screw.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-100 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires high thrust, delivering 15708N of push force even at a conservative 0.5 MPa. If you need less force, stepping down to a 160 mm bore yields 10053N at the same pressure, but the 200 mm bore is necessary for moving heavy masses. The 100 mm adjustment range is ideal for machinery that undergoes frequent product-size changeovers, allowing the retract stop to be fine-tuned on the fly rather than fabricating new hard stops.
Because the stroke is 350 mm, the long unsupported piston rod is susceptible to side-loading and sagging; an external guide rail should be used to prevent premature seal wear. Remember that the rear adjuster acts only as a travel stop to set the end position and deceleration point, not as a locking device. The cylinder cannot hold a load without live air pressure, so for fail-safe load holding, consider an AirTAC SAIL or BSAI series cylinder. This unit is dimensionally interchangeable per ISO 15552 standards and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ200AX350-100 FAQ
At the maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates a maximum push force of 15708N. At a more typical 0.7 MPa, it provides 21991N of push force and 15080N of pull force.
The rear adjuster screw acts as a mechanical stop that trims the effective stroke back from the 350 mm nominal maximum. By turning the screw, you can set the usable travel window anywhere between 250 mm and 350 mm to achieve precise end-position tuning without external stops.
