About the Airtac SAID63 Double Rod Cylinder SAID63X25
The AirTAC SAID63X25 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 25mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on both sides, yielding equal extend and retract forces of 1402N at 0.5MPa. This symmetric thrust makes it highly effective for synchronized motion and dual-side guidance.
Beyond balanced output, the through-rod design allows mounting a workpiece on one end while utilizing the rear extension for a cam, position flag, or secondary mechanism. The extruded aluminum barrel integrates sensor grooves on both sides for flexible CMSE or DMSE switch placement, and adjustable air cushions at both ends manage impact deceleration.

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 SAID63X25 Is Used
Symmetric Force Transfer
Ideal for mechanisms requiring identical push and pull dynamics, where the 1402N output both ways ensures perfectly balanced actuation without pressure compensation.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation during short 25mm strokes, providing precise linear guidance for rigid workholding and clamping tools.
Rear-Rod Cam Actuation
Drive a primary workpiece on the front rod while using the rear protrusion to trigger a mechanical limit switch or actuate a secondary mechanism.
Is the Airtac SAID63 Double Rod Cylinder SAID63X25 the Right Cylinder?
Choose this 63mm bore when an application demands perfectly matched push and pull forces alongside anti-rotation stability that a single-rod SAI cannot provide. If your project requires less force, stepping down to the 50mm bore yields 825N both ways at 0.5MPa; stepping up to the 80mm bore provides 2268N. Ensure your layout accommodates the extra rear-rod clearance required for the through-rod to protrude.
This cylinder uses a G3/8 port and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod variants. It is dimensionally interchangeable per ISO 15552. Note that a plain SAID does not hold its position when air is exhausted; for dead-end load holding, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID63X25 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It delivers 1402N at 0.5MPa, 1962N at 0.7MPa, and 2523N at 0.9MPa.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It supports a specific mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, but omits the FB, CA, CB, and CR options used on single-rod models.
