About the Airtac SAID50 Double Rod Cylinder SAID50AX800S
The AirTAC SAID50X800-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 800mm stroke. Because a piston rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 825N of force in both directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet enables precise position detection using CMSE reed or DMSE solid-state switches.
This through-rod configuration allows you to mount the primary workpiece on one end while attaching a cam, position flag, or secondary mechanism to the rear rod. It utilizes a SUS420J2 stainless steel rod for enhanced durability and features PT tapered port threads. The adjustable air cushions at both ends decelerate the piston near stroke end, but note that this plain cylinder does not hold load or position if air pressure is lost.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX800S Is Used
Symmetric Transfer
Drives loads with identical 825N push and pull force, ensuring stable dynamics during bidirectional material transfer.
Anti-Rotation Slides
The twin-rod architecture prevents the load from twisting, keeping guided slides perfectly aligned over the long 800mm travel.
Dual-Side Actuation
Mount the primary tool on the front rod and a position flag on the rear rod to trigger DMSE sensors at both stroke extremes.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX800S the Right Cylinder?
Choose this 50mm bore model when an application demands 825N of symmetric force and superior anti-rotation guidance that a single-rod SAI cannot provide. If your push or pull requirement is lower, stepping down to the 40mm bore yields 528N both ways; if more force is needed, the 63mm bore offers 1402N. The twin-rod design inherently resists torsional load, making it ideal for twin-station actuation.
At 800mm stroke, the unsupported rod length is substantial, so an external guide is recommended to prevent rod-bearing bending under heavy side loads. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. For applications requiring position holding without live pressure, consider the SAIL or BSAID variants.
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 SAID50 Double Rod Cylinder SAID50AX800S FAQ
It provides an equal 825N of force in both extend and retract directions at 0.5 MPa, reaching 1484N at 0.9 MPa, because the rod occupies both sides of the piston.
No, the adjustable air cushions only decelerate the piston near stroke end; it cannot hold a load without live pressure. For holding, look at the SAIL or BSAID series.
