About the Airtac SAID63 Double Rod Cylinder SAID63X225
The AirTAC SAID63X225 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and a 225mm non-standard stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetric 1402N force at 0.5MPa in either direction. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This through-rod design is ideal for applications requiring dual-side guidance and high anti-rotation resistance. You can mount the primary workpiece on one end and a position flag or cam on the rear rod end. The G3/8 port and M16x1.5 rod thread ensure robust pneumatic flow and secure mechanical attachments for your tooling.

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 SAID63X225 Is Used
Symmetric Force Transfer
Transfers loads with identical push and pull dynamics, ensuring stable motion without the speed fluctuations typical of single-rod cylinders.
Anti-Rotation Slides
Twin rods prevent piston rotation during travel, making it ideal for guiding precision slides and lifting mechanisms.
Through-Rod Sensing
Drives a primary tool on the front stroke while the rear rod end operates a cam or position flag for external limit sensors.
Is the Airtac SAID63 Double Rod Cylinder SAID63X225 the Right Cylinder?
Choose the SAID63X225 when your mechanism requires equal push and pull forces, or needs a rear rod for twin-station actuation and external sensing. If your application needs less force, step down to the 50mm bore (825N at 0.5MPa); for heavier loads, step up to the 80mm bore (2268N at 0.5MPa). As a 225mm stroke exceeds the 200mm standard increment, this is a made-to-order non-standard stroke.
Because the stroke is over 300mm, long unsupported loads can induce side-load bending on the rod bearing; use an external guide for stability. Note that a plain SAID does not hold its position when air is lost—use a SAIL or BSAID cylinder if fail-safe locking is required. This cylinder is dimensionally interchangeable per ISO 15552, using the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT tapered ports.

- ✓ 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 SAID63X225 FAQ
The double-rod design provides equal force in both directions. It delivers 1402N at 0.5MPa, 1962N at 0.7MPa, and 2523N at 0.9MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a standard profile barrel and supports mounting accessories like FA, LB, and TC, but omits FB and CA brackets.
