About the Airtac SAID40 Double Rod Cylinder SAID40AX95
The AirTAC SAID40X95 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 95mm stroke. Because the piston rod extends from both end covers, the annular area is identical on both sides, yielding exactly 528 N of output force in both extend and retract directions at 0.5 MPa. This symmetric force capability is ideal for mechanisms requiring consistent push and pull dynamics.
This specific configuration utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. It features PT tapered port threads and lacks a standard magnet, meaning position sensing requires external flags or limit switches rather than embedded groove sensors. The extruded aluminum barrel maintains a true ISO 15552 mounting footprint for seamless integration.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX95 Is Used
Symmetric Force Transfer
Provides equal 528 N push and pull forces for transferring parts between two parallel workstations without needing to resize valving for directional speed differences.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, serving as a rigid linear slide for lifting and positioning heavy tooling with high repeatability.
Rear-Rod Cam Actuation
The protruding rear rod drives a secondary mechanism or external limit flag, allowing designers to sequence downstream pneumatic actions mechanically.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX95 the Right Cylinder?
Selecting this twin-rod configuration over a standard single-rod SAI cylinder is primarily driven by the need for dual-side guidance, anti-rotation stability, or mounting a secondary cam and position flag on the rear rod extension. If your application requires less force, stepping down to a 32mm bore provides 345 N both ways at 0.5 MPa; conversely, a 50mm bore offers 825 N. The SAID40X95 uses PT ports and supports the reduced double-rod mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Keep in mind that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a related locking type like BSAID for true position holding. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, but external guidance is still recommended for heavy radial loads.
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 SAID40AX95 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers 528 N of force in both the extend and retract directions at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 cylinders. However, the SAID series uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets found on single-rod variants.
