About the Airtac SAID40 Double Rod Cylinder SAID40AX10
The AirTAC SAID40X10 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 10mm stroke. Because a stainless steel SUS420J2 rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 528 N of force in both directions at 0.5 MPa. The PT tapered port threads ensure a tight, reliable pneumatic connection.
This short-stroke design allows you to mount a workpiece on the front rod while using the rear protrusion for a sensor flag, cam, or secondary mechanism. The extruded aluminum barrel includes sensor grooves on both sides, ready for position monitoring, though this specific unit ships without a magnet for electronic sensing.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX10 Is Used
Symmetric Transfer
Drives a transfer mechanism where the 528 N extend and retract forces must be perfectly matched to avoid stalling in either direction.
Twin-Station Actuation
Mounts a primary work tool on the front rod and a secondary cam or position flag on the rear rod to actuate a separate micro-valve at stroke end.
Anti-Rotation Slide
Uses the dual through-rods to guide a sliding carriage, preventing rotational twist that a single-rod cylinder cannot resist.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX10 the Right Cylinder?
Choose this 40mm bore when an application strictly demands equal push and pull forces alongside twin-side guidance, which a standard single-rod SAI cannot provide. If your mechanism requires less force, stepping down to the 32mm bore yields 345 N both ways; if more is needed, the 50mm bore offers 825 N at 0.5 MPa. Keep in mind that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If position holding upon air loss is required, explore the SAIL or BSAID locking variants. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for comparable double-rod cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAID40 Double Rod Cylinder SAID40AX10 FAQ
The double-rod design subtracts the rod area from both sides of the piston, providing an equal 528 N of force in both the extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, the SAID40X10 is dimensionally interchangeable per ISO 15552 and uses a standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), allowing it to serve as a drop-in replacement for other ISO 15552 profile double-rod cylinders.
