About the Airtac SAID63 Double Rod Cylinder SAID63X350S
The AirTAC SAID63X350-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 350mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 1402 N at 0.5 MPa. The -S suffix indicates an integrated magnet for position sensing via AirTAC CMSE reed or DMSE solid-state switches fitted into the dual-side barrel grooves.
This through-rod design allows mounting the primary workpiece on one end while attaching a cam, position flag, or secondary mechanism on the rear rod, providing superior anti-rotation guidance for the load. It uses a PT tapered G3/8 port and adjustable air cushions at both ends (36 mm cushion stroke) to decelerate the piston smoothly.

| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |

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 SAID63X350S Is Used
Symmetric Force Transfer
Ideal for mechanisms requiring identical push and pull dynamics, as the twin rods ensure the effective piston area remains equal in both directions.
Anti-Rotation Slides
The dual-rod construction provides superior lateral guidance and prevents the load from twisting during transit over the 350mm stroke.
Through-Rod Sensing
Mount the primary tool on the front rod and a DMSE sensor flag on the rear rod to track position without interfering with the work area.
Is the Airtac SAID63 Double Rod Cylinder SAID63X350S the Right Cylinder?
Choose this twin-rod actuator over a single-rod SAI when your application demands symmetrical push/pull forces, dual-side guidance against rotation, or rear-rod sensing. At 0.5 MPa it generates 1402 N both ways; if your mechanism requires less force, step down to the 50mm bore (825 N), or step up to the 80mm bore (2268 N) for heavier loads. It is dimensionally interchangeable per ISO 15552 for direct replacement of other double-rod cylinders.
For a 350mm stroke, the unsupported rod length increases side-load risks and rod-bearing bending, so utilizing an external guide is recommended. The mounting accessory set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, select an SAIL, BSAID, or external rod lock.

- ✓ 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 SAID63X350S FAQ
Because the rod occupies both sides of the piston, the extend and retract forces are equal. It delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa in both directions.
Yes, it is dimensionally interchangeable per ISO 15552 and can serve as a direct replacement for other ISO 15552 double-rod profile cylinders, using the standard PT G3/8 port.
