About the Airtac SAID80 Double Rod Cylinder SAID80AX475S
The AirTAC SAID80X475-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 475mm stroke and an 80mm bore. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding exactly 2268N of force at 0.5 MPa on both extend and retract strokes. A single piston drives a rod out of both end covers, allowing you to mount the primary workpiece on one end and a position flag or secondary cam on the rear rod.
This specific variant includes a -S magnet for positioning feedback and uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Operating pressure ranges from 0.15 to 1.0 MPa, and the adjustable air cushions at both ends decelerate the piston near stroke end to minimize impact.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX475S Is Used
Symmetric Force Transfer
Drives a workpiece across a conveyor with identical 2268N push and pull forces at 0.5 MPa, ensuring consistent timing in both motion directions without pressure compensation.
Dual-Station Actuation
Mounts the primary tool on the front rod and a secondary mechanism or cam on the rear rod end to operate two synchronized stations from a single pneumatic source.
Anti-Rotation Slides
Uses the twin-rod architecture to guide heavy loads linearly, preventing the rotational twist that single-rod cylinders experience under offset payloads.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX475S the Right Cylinder?
Choose this 80mm bore double-rod cylinder when an application demands equal push and pull forces—2268N at 0.5 MPa and 3175N at 0.7 MPa—along with superior anti-rotation guidance. If your layout requires less force, the 63mm bore neighbor offers 1402N both ways at 0.5 MPa; stepping up to the 100mm bore yields 3681N. The SAID series uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod SAI models. It is dimensionally interchangeable per ISO 15552 mounting interfaces.
Because the stroke is 475mm, the 25mm rod and its M20x1.5 thread experience higher bending moments under heavy side loads; an external guide is recommended to prevent rod-bearing wear. Note that a plain SAID does not hold its position if air pressure is lost or the valve is centered—the piston will drift. For load-holding requirements without live pressure, consider the SAIL (air-released lock) or BSAID (clamp-lock) variants. This unit uses PT tapered ports and includes the -S magnet for sensor compatibility.

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 SAID80AX475S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers an equal force of 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa in both extend and retract directions.
Yes, the SAID80X475-S is dimensionally interchangeable per ISO 15552 mounting interfaces, allowing it to serve as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a PT G3/8 port and includes a magnet for CMSE/DMSE sensors.
