About the Airtac SAID40 Double Rod Cylinder SAID40X170
The AirTAC SAID40X170 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 170mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on each side, yielding exactly 528 N of force in both extend and retract directions at 0.5 MPa. This symmetric output makes it highly predictable for balanced motion control tasks.
Beyond equal force, the twin-rod architecture allows you to mount a primary workpiece on the front rod and a position flag or cam on the rear rod to trigger external sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT tapered port threads ensure a tight, leak-free pneumatic connection on your G1/4 fittings.

Where the Airtac SAID40 Double Rod Cylinder SAID40X170 Is Used
Symmetric Transfer
Drives a transfer carriage with identical 528 N force and speed in both directions, ensuring perfectly balanced part shuttling without momentum disparities.
Anti-Rotation Slides
The twin-rod geometry resists torsional twisting on linear slides, keeping the tool plate perfectly aligned during vertical or horizontal pressing operations.
Rear-Cam Actuation
Mounts the primary tool on the front rod while using the protruding rear rod to drive a mechanical cam or trigger external limit switches mid-stroke.
Is the Airtac SAID40 Double Rod Cylinder SAID40X170 the Right Cylinder?
Select this 40mm bore when an application demands equal push and pull forces alongside dual-side guidance to prevent rotation. If your mechanism requires less force, stepping down to the 32mm bore provides 345 N each way at 0.5 MPa; if more thrust is needed, the 50mm bore offers 825 N. Since this is a 170mm stroke, it falls within standard limits and avoids the extreme side-loading risks of longer strokes, though external guidance is always recommended for heavy off-center loads.
Choose the SAID double-rod design over a single-rod SAI when you need to drive a secondary mechanism from the rear or require precise anti-rotation stability. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders. Note that a plain SAID does not hold its position if air pressure is lost; for locking requirements, consider the SAIL or BSAID series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAID40X170 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides 528 N of force in both the extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X170 is dimensionally interchangeable per ISO 15552. It shares the same mounting footprint and G1/4 port size as comparable profile cylinders, allowing for a direct drop-in replacement.
