About the Airtac SAID40 Double Rod Cylinder SAID40X65
The AirTAC SAID40X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 65mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in both directions, yielding an equal extend and retract force of 528N at 0.5 MPa. This symmetric output is ideal for applications requiring consistent push and pull dynamics.
A defining advantage of this through-rod design is the ability to mount a workpiece on the front rod end while attaching a position flag or cam to the rear. The extruded aluminum barrel includes sensor grooves on both sides, and the standard carbon steel rods provide robust dual-side guidance to prevent rotation. It operates at speeds from 30-800 mm/s using a PT G1/4 port.

Where the Airtac SAID40 Double Rod Cylinder SAID40X65 Is Used
Symmetric Force Transfer
Drives shuttle mechanisms where the equal 528N push and pull capacity at 0.5 MPa ensures perfectly balanced motion regardless of travel direction.
Through-Rod Rear Sensing
Mounts the primary tool on the front rod and a position flag on the rear protrusion to trigger external reed or solid-state sensors.
Anti-Rotation Slides
Utilizes the dual carbon steel rods to guide the load and prevent torsional twist during extend and retract cycles.
Is the Airtac SAID40 Double Rod Cylinder SAID40X65 the Right Cylinder?
Choose this 40mm bore model when your application requires true bidirectional force and anti-rotation guidance that a single-rod SAI cannot provide. If your project needs slightly less push/pull force, stepping down to the 32mm bore yields 345N each way at 0.5 MPa. Conversely, moving up to the 50mm bore increases the both-way output to 825N.
When selecting mounting accessories, note that SAID supports a reduced set of ISO 15552 attachments: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It deliberately omits the FB, CA, CB, and CR mounts used by single-rod variants. Remember that a plain SAID relies on adjustable air cushions to decelerate the piston at stroke ends; it does not hold position if air pressure is lost. For load-holding requirements, consider the SAIL or BSAID clamp-lock series. As a dimensionally interchangeable ISO 15552 component, it serves as a drop-in replacement for other standard double-rod cylinders.

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 SAID40 Double Rod Cylinder SAID40X65 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It generates 528N of force in both the extend and retract directions at 0.5 MPa (739N at 0.7 MPa).
Yes, the SAID40X65 is dimensionally interchangeable per ISO 15552 profile cylinder standards. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, provided you use the compatible PT G1/4 port and the appropriate mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
