About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40
The AirTAC SAIJ200X90-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive 15708N push force at 0.5 MPa. Its built-in stopper screw allows you to fine-tune the effective travel down to 50 mm from the 90 mm nominal stroke without adding external stops. This makes it highly effective for heavy-duty setups requiring precise end-position calibration during commissioning.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and uses PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-500 mm/s and relies on variable air cushions at both ends to decelerate the heavy 3204 kgf maximum load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40 Is Used
Heavy Press End-Tuning
Dial in the exact 50-90 mm travel window during machine commissioning to perfect heavy pressing operations without swapping out the entire cylinder.
Product Size Changeover
Quickly adjust the retract stopper to handle varying package dimensions on a high-thrust conveyor line, ensuring precise positioning every time.
Heavy-Duty Assembly Stops
Utilize the 15708N push force to drive large components, relying on the rear stopper to set precise end-limits for variable assembly stages.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40 the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands the highest thrust class—stepping down to a 160 mm bore drops your 0.5 MPa push force to 10053N. An adjustable-stroke model like this is selected over a fixed SAI when you need on-the-fly end-position tuning to accommodate product-size changes on a line. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an SAIL or BSAI cylinder.
To replace this ISO 15552 cylinder, match the 200 mm bore, 90 mm stroke, 40 mm adjustment range, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). No magnet is specified, so CMSE or DMSE electronic sensors cannot be used without adding the -S option.

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 SAIJ200AX90-40 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 40 mm, creating a 50-90 mm usable travel window. It only sets the end position and decelerates the load; it does not lock or hold the load without continuous air pressure.
