About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-30
The AirTAC SAIJ200X900-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a massive 28274N of push force at 0.9 MPa. It features a rear mechanical adjuster that permits you to trim the effective travel back by up to 30 mm, establishing a precise 870-900 mm usable stroke window. This on-unit fine-tuning eliminates the need to bolt on external stops or swap cylinders when finalizing end positions at commissioning.
Built with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this 200 mm bore unit is tailored for demanding environments. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of position switches. It is important to note that the rear adjuster acts purely as a travel stop to set deceleration endpoints, not as a locking device, meaning it will not hold a load safely without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-30 Is Used
Heavy Pressing Operations
Provides immense 28274N output at 0.9 MPa for assembly presses, while the 870-900 mm adjustable window allows exact bottoming-out calibration for different material thicknesses.
Pallet Transfer Stops
Deploys a robust 40 mm rod to halt heavy loads on a conveyor line, using the rear stopper to dial in the exact stopping distance during product size changeovers.
Large Machine Setup
Facilitates rapid commissioning on large fabrication machinery by allowing engineers to fine-tune the 900 mm travel end-point on-site without machining custom external spacers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-30 the Right Cylinder?
Selecting this 200 mm bore model makes sense when your application requires the highest thrust tier, as stepping down to a 160 mm bore drops your 0.5 MPa push force from 15708N to 10053N. The 30 mm rear adjustment window is highly beneficial for machine setups requiring variable end stops during product changeovers, providing exact position tuning without replacing the cylinder. Because this is a 900 mm stroke, the 40 mm rod diameter requires an external guide to prevent excessive side-loading and premature seal wear over the long unsupported travel distance. For load-holding requirements without live air pressure, this cylinder is insufficient; you should explore the SAIL series with an air-released lock or the BSAI clamp-lock variant instead. To match this exact configuration, specify the 200 mm bore, 900 mm stroke, 30 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the SUS420J2 rod material.

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 SAIJ200AX900-30 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder generates a maximum push force of 28274N. At the standard 0.5 MPa, it provides 15708N of push force and 15080N of pull force.
The rear adjuster is a mechanical stopper that allows you to shorten the nominal 900 mm stroke by up to 30 mm, giving a usable travel window of 870 to 900 mm. It sets the end position but does not lock the load without live air pressure.
