About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-50S
The AirTAC SAIJ200X210-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position without swapping components. It provides a usable travel window of 160 to 210 mm, giving you 50 mm of precise adjustment flexibility during commissioning or product changeovers. Delivering immense thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnetic piston (-S) for position detection. You can mount AirTAC CMSE reed or DMSE electronic solid-state sensors directly into the dual-side extruded aluminum barrel grooves. The G3/4 PT tapered ports and M36x2 rod thread ensure robust pneumatic connections and high structural rigidity for heavy-duty applications.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-50S Is Used
Heavy Press Tuning
Dial in the exact 160-210 mm end-position during heavy press commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Large Product Diversion
Adjust the retract stroke on the fly during production line changeovers to safely divert packages or pallets of different widths.
Automated Assembly Setup
Fine-tune the clamping reach on large automated assembly fixtures, ensuring precise end-stops are met without reprogramming the entire pneumatic circuit.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-50S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires massive force output, stepping up significantly from a 160 mm bore that yields 10053 N push force at 0.5 MPa. Choose the SAIJ adjustable-stroke design over a fixed SAI model when your machinery requires variable end-stops or on-the-fly product size adjustments. The rear adjuster acts purely as a mechanical stop to set the travel limit; it does not hold the load without live air pressure. For genuine load-holding on failure, integrate an external rod lock or select an AirTAC SAIL or BSAI cylinder.
Because the 210 mm stroke exceeds the 300 mm threshold requiring external guidance, note that even with the rigid 40 mm rod, long unsupported strokes necessitate an external guide to prevent excessive side-loading. This unit is dimensionally interchangeable per ISO 15552 and utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ200BX210-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 210 mm stroke by up to 50 mm, providing an effective travel window of 160 to 210 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
