About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10
The AirTAC SAIJ200X450-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 440 to 450 mm for precise end-position tuning. Built with a SUS304 stainless steel rod and PT tapered ports, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. This heavy-duty actuator handles operating speeds of 30-500 mm/s and features variable air cushions at both ends to manage high kinetic energy.
Instead of relying on fixed stops, the rear adjustment screw allows you to trim the stroke by up to 10 mm during commissioning or product changeovers without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10 Is Used
Heavy-Duty Press Tuning
Dial in the exact 440-450 mm end-stop during machine setup to accommodate different material thicknesses in large-scale pressing operations without external shims.
Product Size Changeover
Quickly adjust the stroke end position by up to 10 mm on automated assembly lines when switching between large product variants, minimizing downtime.
Heavy Load Positioning
Move massive payloads with up to 15708 N of push force at 0.5 MPa, using the fine rear adjustment to set the precise retraction point for heavy material handling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX450-10 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application requires massive thrust, such as 15708 N push at 0.5 MPa, combined with on-the-fly stroke tuning. If your force requirements are lower, stepping down to a 160 mm bore provides 10053 N of push force, but the SAIJ200X450-10 is necessary for heavy pressing or clamping. The SUS304 stainless steel rod offers superior corrosion resistance compared to standard carbon steel, making it suitable for harsher environments.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 450 mm stroke, 10 mm adjustment range, PT port threads, and the required mounting style from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 450 mm stroke is substantial, the 40 mm rod diameter handles significant side loads, but an external guide is still recommended to prevent rod binding. For applications requiring the load to be held without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 SAIJ200BX450-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 440 to 450 mm. It is a travel stop for fine-tuning, not a lock, and cannot hold a load without live air pressure.
