About the Airtac SAID40 Double Rod Cylinder SAID40BX140
The AirTAC SAID40X140 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 140mm stroke. Because the piston rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528N of force in each direction at 0.5 MPa. This symmetric output is ideal for mechanisms requiring identical push and pull dynamics.
This specific configuration utilizes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or mildly chemical environments. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches independently on either end. Note that the rear protruding rod requires additional clearance within your machine frame compared to a standard single-rod SAI cylinder.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX140 Is Used
Symmetric Transfer
Drives a transfer carriage with identical 528N force and speed in both directions, ensuring consistent cycle times for parts shuttling.
Anti-Rotation Slide
Twin SUS304 rods guide the load against torsional twist, maintaining precise vertical alignment for pressing or indexing tasks.
Dual-Station Actuation
Mounts the primary workpiece on the front rod and a secondary cam or limit flag on the rear rod to trigger external sequence valves.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX140 the Right Cylinder?
Select this 40mm bore when an application demands equal 528N thrust both ways, stepping down from the 63mm bore (which provides 1402N) for a more compact footprint, or up from the 32mm bore (345N) when extra side-load capacity is needed. The twin-rod design inherently resists torsional rotation better than a single rod, providing dual-side guidance for lifting or pressing loads. If your mechanism must hold position without live air pressure, this standard cylinder will drift; consider a SAIL lock variant or external pilot-operated check valve.
To match this ISO 15552 dimensionally interchangeable cylinder, specify the 40mm bore, 140mm stroke, PT tapered port threads, and your preferred mounting accessory from the SAID subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). As this model lacks the -S magnet suffix, it cannot host internal CMSE or DMSE sensors without modification.
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 SAID40BX140 FAQ
Because it is a double-rod cylinder, the rod occupies both sides of the piston, making the effective area equal in both directions. It provides 528N of force at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable with standard ISO 15552 profile cylinders. It supports a specific subset of mounts including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR styles which are reserved for single-rod SAI units.
