About the Airtac SAID40 Double Rod Cylinder SAID40BX5S
The AirTAC SAID40X5-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a very short 5mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding equal force and speed in both directions. This model generates 528 N of thrust and pull force at 0.5 MPa, ensuring symmetric motion control.
Equipped with a magnetic piston (-S), it supports AirTAC CMSE reed and DMSE electronic sensors for dual-side position feedback. The SUS304 stainless steel rods (option B) provide excellent corrosion resistance, while the G1/4 PT tapered ports ensure reliable pneumatic connections within a compact footprint.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX5S Is Used
Symmetric Force Transfer
Ideal for short-stroke transfer mechanisms requiring identical push and pull dynamics, utilizing the 528 N both-direction force to move parts evenly without speed discrepancies.
Dual-Side Actuation
Drives two separate tooling stations simultaneously from one piston, using the front rod for the primary work and the rear rod for secondary timing or cam actuation.
Anti-Rotation Guidance
The twin SUS304 rods keep the load perfectly guided against rotation in compact gripping and clamping tasks where external linear guides cannot fit.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX5S the Right Cylinder?
Select this 40mm bore double-rod cylinder when an application requires equal 528 N force both ways and high anti-rotation resistance in a tight space. If your project demands less force, the 32mm bore offers 345 N; if you need more, the 50mm bore provides 825 N at the same 0.5 MPa pressure. The twin-rod design inherently resists torsional loads better than a single-rod SAI cylinder.
For mounting, SAID supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR options found on single-rod variants. Note that the adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load; if position holding without air pressure is required, consider a SAIL or BSAID variant.
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 SAID40BX5S FAQ
Because it is a double-rod cylinder, the output force is equal in both directions. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID40X5-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. You can use it as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing the standard G1/4 port and Basic, FA, LB, or TC mounting interfaces.
