About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100
The AirTAC SAIJ200X190-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its integrated 100mm adjustment screw allows you to dial back the 190mm nominal stroke, creating a highly flexible 90-190mm usable travel window for precise positioning without swapping hardware. The extruded aluminum barrel features dual sensor grooves, though this specific configuration omits the magnet, meaning position sensing requires a separate setup or a different variant.
Built for severe environments, this unit utilizes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. The massive 40mm rod diameter and M36x2 thread provide exceptional rigidity, but because the rear adjuster acts only as a travel stop and not a lock, an external rod lock like the BSAI series is required to hold loads safely without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100 Is Used
Heavy Machinery Changeover
Leverage the 90-190mm travel window to quickly adapt large industrial presses to different product lengths during production line changeovers.
Precision End-Stop Tuning
Use the 100mm rear adjuster to micro-adjust the retract position during commissioning, ensuring exact alignment without adding external mechanical stops.
High-Force Clamping
Apply the 15708N push force at 0.5 MPa to secure heavy workpieces, relying on the SUS420J2 rod for durability in harsh manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-100 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application demands maximum force, such as 21991N push at 0.7 MPa, far exceeding the 10053N push of the 160mm bore variant. The 100mm adjustment range is particularly valuable for product changeovers on large machinery, allowing operators to fine-tune the retract end-position on the fly rather than machining custom spacers. Since the total stroke is under 300mm, external guide requirements are less stringent than on longer strokes, though the heavy rod still handles substantial side loads.
When replacing an existing ISO 15552 cylinder, match the 200mm bore, 190mm stroke, 100mm adjustment, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. The operating speed is rated for 30-500 mm/s, accommodating the slower, high-mass movements typical of 200mm bore pneumatics.

- ✓ 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 SAIJ200AX190-100 FAQ
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 190mm nominal stroke by up to 100mm, providing a usable travel window of 90-190mm. The adjuster functions only as a travel stop and does not lock the load without live air pressure.
