About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-10S
The AirTAC SAIJ200X20-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a massive 15708N push force at 0.5 MPa and a 10-20mm usable travel window, allowing you to dial back the nominal 20mm stroke by up to 10mm during commissioning. This fine-tuning capability eliminates the need to swap cylinders or bolt on external stops to achieve precise end positions.
Built for demanding environments, this model uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It features PT tapered port threads (G3/4) and operates at speeds of 30-500mm/s. The extruded aluminum barrel provides sensor grooves on both sides, and the rear adjuster acts strictly as a travel stop, meaning live air pressure is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact clamping end-position on high-force pressing operations within the 10-20mm window without changing the cylinder.
Machine Changeover
Quickly adjust the rear stop for short-stroke product size changes on a line, avoiding the need to swap out the entire actuator.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for heavy-duty positioning tasks in wash-down or corrosive manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX20-10S the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme thrust up to 15708N at 0.5 MPa, stepping up significantly from a 160mm bore that offers 10053N. The 10-20mm adjustable travel window is ideal for setups needing exact short-stroke end-position tuning without external stops. For load-holding without live air pressure, note that this adjuster is a stop, not a lock; you would need an external rod lock, a pilot-operated check valve, or a related AirTAC type like SAIL or BSAI.
Because the 20mm stroke is well under the 300mm side-load threshold, external guides are less critical here, though the robust 40mm rod and M36x2 thread handle high stress well. This SAIJ configuration is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Ensure your system uses PT tapered ports and CMSE or DMSE sensors compatible with the -S magnet.

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 SAIJ200BX20-10S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 20mm stroke by up to 10mm, creating a 10-20mm usable travel window. It functions as a mechanical stop to fine-tune the end position, but it is not a lock and requires live air to hold the load.
