About the Airtac SAID63 Double Rod Cylinder SAID63X800S
The AirTAC SAID63X800-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a substantial 800mm stroke and an integrated magnet. Because the piston rod exits both end covers, the effective annulus area is identical on both sides. This means the extend and retract forces are perfectly equal, delivering 1402N of thrust each way at 0.5 MPa.
The extended rear rod is highly practical for driving a secondary mechanism or mounting a position flag. Equipped with standard carbon steel rods and PT threaded ports, this extruded aluminum body includes dual sensor grooves for CMSE reed and DMSE electronic switches. Note that the through-rod design requires extra rear clearance to accommodate the protruding rod.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID63 Double Rod Cylinder SAID63X800S Is Used
Symmetric Transfer
Drives a heavy workpiece between two stations with equal 1402N force and consistent speed in both directions.
Anti-Rotation Slide
Utilizes the twin-rod geometry to guide a vertical lifting slide over 800mm, preventing unwanted mechanical twist.
Rear-Cam Actuation
Mounts a cam or position flag on the rear rod to trigger external DMSE electronic sensors during the stroke cycle.
Is the Airtac SAID63 Double Rod Cylinder SAID63X800S the Right Cylinder?
Choose this 63mm bore when an application demands symmetric force and speed in both directions, or when rear-side sensing is required over a long 800mm stroke. If your project needs less force, the 50mm bore offers 825N at 0.5 MPa; for heavier loads, the 80mm bore provides 2268N. Because this is a through-rod design, it provides superior anti-rotation guidance compared to a single-rod SAI.
For an 800mm stroke, the 20mm rod and M16x1.25 thread face significant bending moments under side loads; an external guide rail is strongly recommended to prevent premature bearing wear. This cylinder uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552 but does not hold position pneumatically—if air pressure is lost, the piston will drift, requiring an external rod lock or SAIL variant for safety.
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 SAID63 Double Rod Cylinder SAID63X800S FAQ
Because the double-rod design has the same effective piston area on both sides, it provides equal force in both directions. It outputs 1402N at 0.5 MPa, 1962N at 0.7 MPa, and 2523N at 0.9 MPa for both extension and retraction.
Yes, it shares standard ISO 15552 mounting interface dimensions, making it a direct replacement for other ISO 15552 double-rod profile cylinders. Just ensure you use the compatible SAID mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2) and account for the rear rod protrusion.
