About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-30
The AirTAC SAIJ200X180-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It provides a usable travel window of 150-180 mm, allowing you to dial back the nominal 180 mm stroke by up to 30 mm during commissioning. At 0.5 MPa, it generates 15708 N of push force and 15080 N of pull force, making it suitable for high-load pressing and forming tasks.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear stopper acts purely as a travel end-deceleration device, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-30 Is Used
Heavy-Duty Pressing
Apply up to 15708 N of push force for assembling large components, using the 30 mm adjustment to set precise bottoming depth without mechanical shims.
Product Size Changeovers
Adapt automated machinery to different product heights by dialing the stroke back from 180 mm to 150 mm directly at the rear stopper during line setup.
Heavy Forming Operations
Execute high-force bending or straightening tasks where the exact end-position must be tuned on-site, utilizing the robust SUS304 rod for durability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-30 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053 N of push force at 0.5 MPa. The adjustable 150-180 mm travel window is ideal for product changeovers on a line, letting you fine-tune the end position without swapping the cylinder or adding external stops. For load-holding requirements without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
Because the 180 mm stroke is relatively short for this massive bore, side-load risks are minimized compared to longer strokes, but proper mounting alignment remains critical. This model supports a reduced set of ISO 15552 mounting options: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It operates at speeds of 30-500 mm/s and features variable air cushions at both ends to manage kinetic energy.

- ✓ 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 SAIJ200BX180-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the effective travel by up to 30 mm, creating a usable stroke window of 150-180 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
