About the Airtac SAID40 Double Rod Cylinder SAID40BX110
The AirTAC SAID40X110 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 110 mm stroke. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 528 N of force in both extend and retract directions at 0.5 MPa. This symmetric thrust makes it perfect for operations requiring equal push and pull dynamics.
Equipped with a SUS304 stainless steel rod and PT tapered port threads, this variant is built for robust performance. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches if a magnet is added later. The rear rod extension is fully functional, allowing you to mount a cam, position flag, or secondary mechanism while keeping the load guided against rotation.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX110 Is Used
Symmetric Transfer
Provides equal 528 N push and pull force at 0.5 MPa, ensuring perfectly balanced transfer of workpieces without speed variations between stroke directions.
Anti-Rotation Guidance
The twin-rod design naturally resists torsional movement, keeping heavy loads guided and preventing rotation without needing external linear bearings.
Dual-Mechanism Drive
Mount the primary workpiece on the front rod and a secondary cam, limit flag, or sensor target on the rear rod to actuate two stations simultaneously.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX110 the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm (345 N) or larger 50 mm (825 N) is ideal when your application demands roughly 500 N of symmetric force. A double-rod design is chosen over a single-rod SAI when you need dual-side guidance, anti-rotation control, or rear-rod sensing. Remember that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will drift if air pressure is lost. For position holding without live pressure, consider an external rod lock or the SAIL/BSAID series.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since the stroke is 110 mm, side-load risks are minimal, but always ensure proper alignment to prevent rod-bearing wear.

- ✓ 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 SAID40BX110 FAQ
Because the double-rod design occupies piston area on both sides, it provides equal force in both directions. It delivers 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, it is dimensionally interchangeable per ISO 15552 standards. However, the SAID series uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support FB, CA, CB, or CR mounts found on single-rod variants.
