About the Airtac SAID50 Double Rod Cylinder SAID50BX1000
The AirTAC SAID50X1000 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 1000 mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal extend and retract force of 825 N at 0.5 MPa. This symmetric output is ideal for applications requiring consistent push and pull dynamics.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. A rod exits both end covers, allowing you to mount the primary workpiece on one end and a position flag or secondary cam on the rear. It shares the standard extruded aluminum barrel with dual sensor grooves, compatible with AirTAC CMSE and DMSE switches if a magnet is specified later.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX1000 Is Used
Symmetric Force Transfer
Delivers equal 825 N push and pull forces for material handling systems requiring consistent kinetic output in both directions.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, ensuring precise linear guidance for external tools and workpieces.
Rear-Rod Sensing
Mounts a position flag or cam on the rear rod extension to trigger external limit sensors without interfering with the primary load.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX1000 the Right Cylinder?
Choose this 50 mm bore when an application demands 825 N of symmetric force both ways; step down to a 40 mm bore (528 N) for lighter loads or up to a 63 mm bore (1402 N) when heavier thrust is required. The double-rod design is selected over a single-rod SAI when twin-side guidance, anti-rotation stability, or rear-rod actuation is needed. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders.
At 1000 mm stroke, the unsupported rod length increases bending moments on the rod bearing; an external guide is recommended to handle side loads. Note that a plain SAID does not hold its position when air is lost—the adjustable air cushions only decelerate the piston near stroke end. For load-holding without live pressure, consider an external rod lock or the BSAID clamp-lock series. Mounting options include the reduced SAID set: Basic, FA, LB, TC, FTC, TCM1, TCM2.

- ✓ 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 SAID50 Double Rod Cylinder SAID50BX1000 FAQ
It provides an equal force of 825 N at 0.5 MPa in both extend and retract directions, reaching 1154 N at 0.7 MPa, because the double-rod design balances the piston annulus area.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards. You can use it as a drop-in replacement matching the 50 mm bore, 1000 mm stroke, and PT port interface.
