About the Airtac SAID40 Double Rod Cylinder SAID40AX600
The AirTAC SAID40X600 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 600 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528 N of force in both directions at 0.5 MPa (739 N at 0.7 MPa). The piston travels at 30-800 mm/s and uses adjustable air cushioning at both ends to decelerate near stroke limits.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. PT tapered port threading and a G1/4 connection are standard for this bore. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit is configured without a magnet for position sensing.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX600 Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with identical 528 N force on both strokes, ensuring perfectly balanced timing for parts shifting and transfer operations.
Anti-Rotation Slides
The twin-rod geometry prevents piston rotation, providing precise linear guidance for lifting and pressing tools without external guide rails.
Rear-Mounted Cam Actuation
Mount the primary tool on the front rod end and use the rear protruding rod to drive a secondary mechanism or mechanical cam over the 600 mm travel.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX600 the Right Cylinder?
Select this 40 mm bore when an application requires equal push and pull forces, as the twin-rod design provides 528 N both ways at 0.5 MPa. If your mechanism needs higher thrust, stepping up to the 50 mm bore yields 825 N, while dropping to a 32 mm bore reduces output to 345 N. The double-rod architecture is ideal for anti-rotation slides, twin-station actuation, or mounting a rear cam and position flag.
At a 600 mm stroke, the unsupported rod length increases the risk of rod-bearing bending under side loads; always use an external guide rail to support the workpiece. Remember that the adjustable air cushions only decelerate the piston at end-of-stroke and do not hold the load if air pressure is lost. For position holding without live pressure, consider an external pilot-operated check valve or the SAIL/BSAID locking variants. This cylinder is dimensionally interchangeable per ISO 15552 and uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod SAI models.

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 SAID40AX600 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa in both directions.
Yes, the SAID40X600 is a profile-type extruded aluminum cylinder that is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, using the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
