About the Airtac SAID50 Double Rod Cylinder SAID50AX65
The AirTAC SAID50X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 65 mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract. This yields exactly 825 N of force in both directions at 0.5 MPa, ensuring perfectly symmetric thrust and speed for demanding transfer tasks.
This specific configuration utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, allowing you to mount position switches independently on either end to track both rod extensions.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX65 Is Used
Symmetric Force Transfer
Ideal for moving loads between two stations where the 825 N thrust must remain identical in both directions without speed fluctuations.
Anti-Rotation Slides
The dual-rod geometry prevents piston twist, providing precise linear guidance for vertical lifting slides and tooling fixtures.
Rear-End Position Flagging
The protruding rear rod serves as a mounting point for a cam or physical limit flag, allowing external mechanical tracking of the stroke.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX65 the Right Cylinder?
Select this 50 mm bore when an application demands equal push and pull forces, such as 825 N at 0.5 MPa. If your mechanism requires less thrust, stepping down to the 40 mm bore provides 528 N both ways; for heavier loads, the 63 mm bore offers 1402 N. The twin-rod design is chosen over a single-rod SAI when you need dual-side guidance to prevent rotation, or when a rear rod end is required to mount a cam or position flag.
This model uses PT ports and is dimensionally interchangeable per ISO 15552. Note that a plain SAID cylinder does not hold its position if air pressure is lost; use an external pilot-operated check valve or explore the SAIL lock variant if mid-stroke holding is required. Since the stroke is 65 mm, side-load stress on the rod bearing is minimal and does not require external guides.
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 SAID50 Double Rod Cylinder SAID50AX65 FAQ
Because it is a double-rod cylinder, the rod occupies both sides of the piston, making the effective area equal. It provides 825 N of force in both the extend and retract directions at 0.5 MPa, and 1154 N at 0.7 MPa.
Yes, the SAID50X65 is a profile cylinder dimensionally interchangeable per ISO 15552. It can serve as a drop-in replacement for other ISO 15552 double-rod cylinders with a 50 mm bore and 65 mm stroke, using the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
