About the Airtac SAID63 Double Rod Cylinder SAID63X400S
The AirTAC SAID63X400-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a magnetic piston for position sensing. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract. This yields exactly 1402 N of force in both directions at 0.5 MPa, ensuring perfectly symmetric speed and thrust for demanding transfer tasks.
The twin-rod architecture allows you to mount the primary workpiece on the front rod while using the rear extension for a cam, limit flag, or secondary mechanism. Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves. Note that the through-rod design requires extra rear clearance compared to a single-rod SAI.

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 SAID63X400S Is Used
Symmetric Force Transfer
Drives shuttle mechanisms where identical 1402 N thrust and matching speeds in both directions prevent jerky transitions and ensure smooth payload handling.
Anti-Rotation Slides
The twin-rod geometry inherently resists torsional twisting, providing stable linear movement for heavy vertical lifting slides without external guides.
Dual-Station Actuation
Mounts a primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger DMSE electronic sensors at separate machine stations.
Is the Airtac SAID63 Double Rod Cylinder SAID63X400S the Right Cylinder?
Select this 63 mm bore when an application demands equal push and pull forces, which eliminates the speed differential found in single-rod cylinders. If your project requires less thrust, stepping down to the 50 mm bore yields 825 N both ways at 0.5 MPa; stepping up to the 80 mm bore provides 2268 N. This double-rod configuration is specifically chosen over a standard SAI when dual-side guidance, anti-rotation stability, or rear-rod actuation is required.
At 400 mm of stroke, the unsupported rod length increases susceptibility to bending under side loads, so utilizing an external guide rail is highly recommended. Mounting options are limited to the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552. Remember that the adjustable air cushions only decelerate the piston near stroke ends; this cylinder will drift and cannot hold a load if air pressure is lost.
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 SAID63X400S FAQ
Because the double-rod design occupies equal area on both sides of the piston, it provides 1402 N of force in both extend and retract directions at 0.5 MPa, and 1962 N at 0.7 MPa.
Yes, the SAID63X400-S shares the exact ISO 15552 mounting interface dimensions, making it a direct replacement for comparable ISO 15552 double-rod profile cylinders. It uses a G3/8 port and PT tapered threads.
