About the Airtac SAID80 Double Rod Cylinder SAID80BX45S
The AirTAC SAID80X45-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 45mm stroke and an integrated magnet for position sensing. Because the piston rod exits both end covers, the annular effective area is identical in both directions, yielding exactly 2268N of force at 0.5MPa on both extend and retract strokes. The twin rods provide superior anti-rotation guidance and allow mounting a secondary tool or cam on the rear rod end.
This variant is built with SUS304 stainless steel rods (material code B) for superior corrosion resistance and includes a magnet compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel features sensor grooves on both sides, and the adjustable air cushions at both ends provide 36mm of deceleration to protect your tooling.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX45S Is Used
Symmetric Force Transfer
Drives a workpiece with identical 2268N push and pull force, ensuring perfectly balanced motion for transfer arms and indexing units.
Anti-Rotation Slides
Twin 25mm SUS304 rods guide the load against rotational torque, maintaining precise angular alignment for sliding carriage assemblies.
Through-Rod Sensing
The rear rod extension provides a mounting point for a cam or flag, triggering DMSE electronic sensors to confirm end-of-stroke position.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX45S the Right Cylinder?
Choose this 80mm bore when an application requires symmetric force and speed both ways, stepping up from the 63mm bore (1402N at 0.5MPa) or down from the 100mm bore (3681N at 0.5MPa). A double-rod design is selected over a single-rod SAI when the mechanism demands dual-side guidance to prevent rotation, or when a rear-position flag is needed to trigger CMSE/DMSE sensors. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders using the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), with PT tapered port threads.
Note that the adjustable air cushions only decelerate the piston near stroke end; they do not lock or hold the load if air pressure is lost. If your application requires position holding without live pressure, consider the SAIL (air-released lock) or BSAID (clamp-lock) variants. Because the stroke is 45mm, side-load bending moments on the 25mm rod bearings are minimal, but external guides are always recommended for heavy off-center loads.

- ✓ 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 SAID80 Double Rod Cylinder SAID80BX45S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa in both directions.
Yes, as a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features a G3/8 port.
