About the Airtac SAID63 Double Rod Cylinder SAID63X400
The AirTAC SAID63X400 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 400mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on each side, yielding exactly 1402 N of force in both extend and retract directions at 0.5 MPa. This symmetric output is perfect for twin-station actuation or driving a secondary mechanism from the rear rod end.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this unit is configured without a magnet. It features PT tapered port threads (G3/8) and adjustable air cushions at both ends to decelerate the piston smoothly. Note that the through-rod design requires additional 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 SAID63X400 Is Used
Twin-Station Actuation
Drives two separate workstations simultaneously from a single piston, utilizing the equal 1402 N force and speed on both the extend and retract strokes.
Anti-Rotation Slides
The dual-rod geometry prevents the load from twisting during vertical or horizontal transfer, providing stable guidance without external rails.
Rear-End Sensing
Mounts a physical cam or limit flag on the protruding rear rod end to trigger external mechanical switches independently of the primary tool.
Is the Airtac SAID63 Double Rod Cylinder SAID63X400 the Right Cylinder?
Select this 63mm bore double-rod cylinder when an application demands equal push and pull forces, such as 1402 N each way at 0.5 MPa, or anti-rotation guidance. If your project requires less force, the 50mm bore offers 825 N; if you need more, the 80mm bore provides 2268 N. A double-rod design is chosen over a single-rod SAI when you need to mount a cam or position flag on the rear rod, or drive two synced loads. As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other standard double-rod cylinders. To match this configuration, specify the 63mm bore, 400mm stroke, PT port thread, and your preferred mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 400mm, the unsupported rod length increases the risk of side-load bending; an external guide bearing should be used to support the load. Remember that the adjustable air cushion only decelerates the piston near stroke end and does not hold the load if air pressure is lost. For position holding without live pressure, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.

- ✓ 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 SAID63X400 FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. The cylinder generates 1402 N of force at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa on both the extend and retract strokes.
No, the adjustable air cushions only decelerate the piston at the stroke ends and do not act as a brake. The piston will drift if air is exhausted or pressure drops. For dead-load holding, use a SAIL lock cylinder, a BSAID clamp-lock, or an external rod lock.
