About the Airtac SAID80 Double Rod Cylinder SAID80BX800
The AirTAC SAID80X800 is a double-acting, double-rod ISO 15552 profile cylinder featuring an 80mm bore and an 800mm stroke. Because the twin rods occupy both sides of the piston, the effective annulus area is identical in each direction, yielding exactly 2268N of force at 0.5 MPa on both extend and retract strokes. This equal-force symmetry is ideal for applications requiring consistent dynamics without favoring the push or pull phase.
This specific configuration incorporates SUS304 stainless steel rods (material code B) for enhanced corrosion resistance and includes PT tapered port threads (G3/8). The extruded aluminum barrel integrates sensor grooves on both sides, though this unit lacks the -S magnet option. Note that the through-rod design requires extra rear clearance, as the rod protrudes from the back end cover during operation.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX800 Is Used
Symmetric Force Transfer
Drives a heavy workpiece back and forth across a processing station with identical 2268N push and pull force, ensuring consistent cycle times regardless of travel direction.
Anti-Rotation Slides
Uses the dual through-rods to guide a heavy precision fixture, preventing rotational twist during vertical or horizontal clamping operations.
Dual-Side Actuation
Mounts the primary workpiece on the front rod and a secondary cam or limit flag on the rear rod to trigger external sequence valves at stroke endpoints.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX800 the Right Cylinder?
Selecting this 80mm bore makes sense when your mechanism requires 2268N of symmetric force at 0.5 MPa, stepping up from the 63mm bore which provides 1402N. If your load is lighter, the 63mm variant saves space, but the 80mm bore is necessary for heavier anti-rotation slides or dual-station actuation. The double-rod architecture is chosen over a single-rod SAI specifically when you need to mount a cam, position flag, or secondary tool on the rear rod extension while maintaining superior guidance against torsion.
At an 800mm stroke, the unsupported rod length is significant. Even with the robust 25mm diameter rods and M20x1.5 rod threads, side-load inertia will induce bending moments on the rod bearings. You must use an external guide rail to support the load and prevent premature seal wear. Remember that a plain SAID cylinder relies on live air pressure to hold its position; if air is lost, the piston drifts. For fail-safe load holding without pressure, consider an external rod lock or the BSAID clamp-lock variant. This model is dimensionally interchangeable per ISO 15552 mounting interfaces and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAID80 Double Rod Cylinder SAID80BX800 FAQ
Because it is a double-rod cylinder, the rod area is subtracted from both sides of the piston, making extend and retract forces equal. It outputs 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa in both directions.
Yes, the SAID80X800 is dimensionally interchangeable per ISO 15552 profile cylinder mounting interfaces. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories, allowing it to drop into existing machinery setups designed for standard ISO 15552 double-rod cylinders.
