About the Airtac SAID63 Double Rod Cylinder SAID63X900
The AirTAC SAID63X900 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and a 900mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on both sides, generating an equal 1402N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for applications requiring consistent push and pull dynamics.
Beyond balanced force, the twin-rod architecture provides superior anti-rotation guidance for the load. The rear rod extension can be utilized to mount a cam or secondary mechanism. It features adjustable air cushions at both ends to decelerate the piston near stroke limits, and the extruded aluminum barrel includes dual-side sensor grooves for flexible positioning switch placement.

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 SAID63X900 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where identical push and pull thrust is required, ensuring consistent acceleration and deceleration regardless of travel direction.
Anti-Rotation Slides
Guides a heavy vertical lifting slide over 900mm without twisting, using the twin-rod design to maintain precise linear motion under offset loads.
Rear-Cam Actuation
Uses the protruding rear rod end to trigger an external mechanical limit valve or cam mechanism, keeping the primary front rod dedicated to the main workload.
Is the Airtac SAID63 Double Rod Cylinder SAID63X900 the Right Cylinder?
Choose this 63mm bore model when an application demands exact bidirectional force and high torsional stability over a long 900mm stroke. If your project requires less force, stepping down to the 50mm bore yields 825N both ways at 0.5 MPa, but the 63mm bore offers a larger 20mm rod thread that better handles mechanical stress. Conversely, if you need greater thrust, the 80mm bore provides 2268N both ways.
Because this cylinder features a 900mm stroke, the extended unsupported rod length increases the risk of side-load bending and rod-bearing wear; utilizing an external guide is highly recommended to prevent premature seal failure. Ensure your setup accommodates the longer overall length, as the rear rod protrudes from the back cover and requires clearance. This model uses a PT port thread and accepts AirTAC CMSE reed and DMSE electronic sensors in the dual grooves. Note that the air cushions only decelerate the piston and do not hold a load; if position holding without live pressure is required, consider the SAIL or BSAID series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAID63X900 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers an equal 1402N of force in both extend and retract directions at 0.5 MPa, and 1962N at 0.7 MPa.
Yes, the SAID63X900 is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 profile double-rod cylinders, matching standard mounting interfaces and bore dimensions.
