About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-50
The AirTAC SAIJ200X900-50 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 stroke adjuster that creates an 850-900mm usable travel window, allowing you to dial back the nominal 900mm stroke by up to 50mm during commissioning. This eliminates the need to swap cylinders or bolt on external stops when finalizing end positions.
Built with a robust 40mm SUS304 stainless steel rod and M36x2 rod threads, this unit handles extreme loads effectively. It uses PT tapered port threads (G3/8) and includes variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel features sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE solid-state sensors if you add a magnet later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-50 Is Used
Heavy Press Tuning
Fine-tune the 850-900mm travel window on large metal forming presses to accommodate varying material thicknesses without changing tooling.
Large Product Changeover
Adjust the rear stopper by up to 50mm to handle different pallet or product lengths on a heavy-duty conveyor line.
Automated Assembly Stops
Set precise end positions for large-scale robotic assembly cells, using the 28274N force to drive heavy components into place.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-50 the Right Cylinder?
Choose this 200mm bore when the 160mm class (18095N push at 0.9 MPa) is insufficient for your pressing or heavy lifting demands. The 50mm adjustment range is ideal for product changeovers on large machines, letting you shift the end-stop without mechanical rework. For a fixed end position without fine-tuning, the standard SAI cylinder is a simpler alternative.
Because the 900mm stroke is substantial, an external guide is strongly recommended to prevent side-load damage to the 40mm rod and seals. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 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 SAIJ200BX900-50 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm, providing a usable travel window of 850-900mm. It acts as a mechanical stop to fine-tune the retract position and does not lock the load without live air pressure.
At 0.9 MPa, the SAIJ200X900-50 delivers 28274N of push force and 15080N of pull force. It operates at speeds of 30-500 mm/s and uses a 40mm SUS304 stainless steel rod for high load capacity.
