About the Airtac SAID63 Double Rod Cylinder SAID63X125
The AirTAC SAID63X125 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 125mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on both sides, yielding exactly 1402 N of force in both extend and retract directions at 0.5 MPa. It uses PT tapered ports sized at G3/8 and includes adjustable air cushions at both ends.
This through-rod design allows you to mount the primary workpiece on one end and a position flag or cam on the opposite rear rod end. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific unit ships without a magnet.

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 SAID63X125 Is Used
Symmetric Force Transfer
Drives mechanisms where the push and pull strokes must move identical loads at matching speeds without requiring flow controls to balance the differential areas.
Dual-Side Actuation
Mounts a primary work tool on the front rod end while utilizing the rear protruding rod to operate a secondary mechanism or mechanical cam.
Anti-Rotation Slides
The twin-rod configuration provides enhanced resistance to torsional twist and side-load rotation, keeping guided loads perfectly stable throughout the stroke.
Is the Airtac SAID63 Double Rod Cylinder SAID63X125 the Right Cylinder?
Select this 63mm bore when an application requires 1402 N of symmetric force and superior anti-rotation guidance compared to a single-rod SAI. If your mechanism needs less push, the 50mm bore offers 825 N both ways; if you need more power, stepping up to the 80mm bore provides 2268 N. Remember that a plain SAID does not hold its load when air pressure is lost or the valve is centered—the piston will drift. For position-holding needs, consider the SAIL or BSAID variants.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard double-rod profile cylinders. It supports a reduced set of mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR variants used only on single-rod models. Operating speed ranges from 30-800 mm/s.
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 SAID63X125 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers 1402 N of force in both the extend and retract directions at 0.5 MPa, and 1962 N at 0.7 MPa.
Yes. The SAID63X125 is dimensionally interchangeable per ISO 15552 mounting interface dimensions, making it a direct replacement for other standard double-rod profile cylinders. It uses a G3/8 PT port.
