About the Airtac SAID40 Double Rod Cylinder SAID40BX10
The AirTAC SAID40X10 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding exactly 528N of force in both extend and retract directions at 0.5MPa.
This specific configuration features a highly corrosion-resistant SUS304 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, allowing you to mount CMSE or DMSE switches on either side to track the short 10mm stroke precisely.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX10 Is Used
Symmetric Force Transfer
Ideal for shuttle mechanisms requiring identical 528N push and pull forces to maintain consistent cycle timing without pressure compensation.
Anti-Rotation Slides
The twin-rod architecture prevents piston twisting during the short 10mm stroke, ensuring precise linear guidance for clamping or gauging.
Dual-Side Actuation
Drive a primary tool on the front rod while using the rear protrusion to trigger an external DMSE solid-state sensor for confirmation.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX10 the Right Cylinder?
Select this 40mm bore cylinder when an application demands equal push and pull forces, such as 528N at 0.5MPa, alongside inherent anti-rotation guidance from the twin rods. If your mechanism requires less force, stepping down to the 32mm bore offers 345N both ways; if more thrust is needed, the 50mm bore provides 825N.
Choose the SAID double-rod design over a single-rod SAI when you need to drive a workpiece on one end while mounting a cam or position flag on the rear rod. Note that this standard cylinder does not hold position upon air loss; for locking requirements, consider the SAIL or BSAID series. As a dimensionally interchangeable ISO 15552 unit, it serves as a drop-in replacement matching the 40mm bore, 10mm stroke, PT ports, and standard mounting accessories.

- ✓ 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 SAID40BX10 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers 528N of force in both the extend and retract directions at 0.5MPa, and 739N at 0.7MPa.
Yes, the SAID40X10 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface and footprint as comparable double-rod profile cylinders, allowing for a direct drop-in replacement.
