About the Airtac SAID63 Double Rod Cylinder SAID63X120S
The AirTAC SAID63X120-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 120mm stroke. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 1402 N output force at 0.5 MPa in either direction. The integrated -S magnet enables position tracking via CMSE reed or DMSE solid-state switches.
This through-rod layout is ideal for applications requiring dual-side guidance or anti-rotation. You can mount the primary workpiece on the front rod end and a cam, position flag, or secondary mechanism on the rear. The extruded aluminum barrel includes sensor grooves on both sides, and the overall length requires extra clearance for the protruding rear rod.

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 SAID63X120S Is Used
Symmetric Force Transfer
Drives dual-sided push/pull mechanisms where equal 1402 N force and speed in both directions prevent mechanical binding.
Anti-Rotation Slides
The twin through-rods provide inherent torsional resistance, keeping guided loads stable without external linear bearings.
Rear-End Sensing & Cams
Mounts a CMSE/DMSE sensor flag or cam on the rear rod end to trigger secondary operations without interfering with the primary work area.
Is the Airtac SAID63 Double Rod Cylinder SAID63X120S the Right Cylinder?
Select this 63mm bore model when your mechanism demands symmetric push and pull forces, needing 1402 N at 0.5 MPa (or 1962 N at 0.7 MPa) in both directions. If your application requires less force, the 50mm bore offers 825 N at 0.5 MPa; for heavier loads, the 80mm bore provides 2268 N. This double-rod design is preferred over a single-rod SAI when twin-station actuation or rear-rod sensing is required.
Ensure your layout accommodates the PT G3/8 port and the rear rod protrusion. The adjustable air cushions at both ends decelerate the piston near stroke limits but do not hold a load if air pressure drops. For position holding without live pressure, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external rod lock. This model is dimensionally interchangeable per ISO 15552 for direct replacement of other standard double-rod profile cylinders.
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 SAID63X120S FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa in both the extend and retract directions.
Yes. The SAID63X120-S is built to ISO 15552 mounting interface dimensions, making it a direct replacement for other standard ISO 15552 double-rod profile cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features a PT G3/8 port.
