About the Airtac SAID50 Double Rod Cylinder SAID50BX5S
The AirTAC SAID50X5-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 5mm stroke. Because a piston rod exits both end covers, the annulus area is identical on extension and retraction, yielding an equal 825N of force in both directions at 0.5 MPa. This specific configuration includes a magnet for position sensing and utilizes SUS304 stainless steel rods (code B) for enhanced corrosion resistance.
Beyond symmetric thrust, the through-rod design allows engineers to mount the primary workpiece on one end and a secondary component—such as a cam, position flag, or second tool—on the rear rod end. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX5S Is Used
Short-Stroke Clamping
Ideal for high-cycle clamping tasks where the 5mm stroke provides rapid engagement and the equal 825N both-way force ensures consistent holding pressure.
Symmetric Transfer
Drives transfer mechanisms where the load must be pushed and pulled at identical speeds, utilizing the matched annulus area of the double-rod design.
Rear-Rod Cam Actuation
The protruding rear rod acts as a mechanical cam or trigger for secondary sequencing, while the front rod executes the primary work stroke.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX5S the Right Cylinder?
Select this 50mm bore model when an application demands equal push and pull forces—825N each way at 0.5 MPa—and a very short 5mm stroke for high-cycle clamping or pressing. If your mechanism requires less force, stepping down to the 40mm bore provides 528N both ways, while moving up to the 63mm bore offers 1402N. The twin-rod architecture is chosen over a single-rod SAI when the load requires anti-rotation guidance or dual-side actuation. Note that the SAID mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on single-rod cylinders.
This configuration uses PT tapered port threads and a magnet for sensing. Because the stroke is only 5mm, side-load bending on the rod bearing is negligible. However, a plain SAID does not hold its position if air pressure is lost; the piston will drift. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAID clamp-lock cylinder, or an external pilot-operated check valve.

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 SAID50 Double Rod Cylinder SAID50BX5S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa for both extension and retraction.
Yes, the SAID50X5-S is dimensionally interchangeable per ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses a G1/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
