About the Airtac SAID63 Double Rod Cylinder SAID63X500S
The AirTAC SAID63X500-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 500mm stroke. Because a carbon steel rod extends from both end covers, the effective piston area is identical in both directions, yielding an equal extend and retract force of 1402N at 0.5MPa. The integrated -S magnet allows seamless position detection using AirTAC CMSE reed or DMSE solid-state switches along the dual sensor grooves.
This through-rod architecture provides superior anti-rotation guidance and allows a secondary mechanism or limit flag to be mounted on the rear rod end. It utilizes a PT tapered port thread (G3/8) and includes adjustable air cushions at both ends to decelerate the piston smoothly. It is dimensionally interchangeable per ISO 15552 standards for direct replacement scenarios.

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 SAID63X500S Is Used
Symmetric Force Transfer
Ideal for transferring loads where the push and pull forces must be perfectly matched, utilizing the equal 1402N annulus area in both directions.
Twin-Station Actuation
Drive two separate mechanisms simultaneously by mounting a workpiece on the front rod and a secondary tool or cam on the rear protruding rod end.
Dual-Side Position Sensing
The -S magnet works with CMSE and DMSE switches in the dual barrel grooves, allowing independent position flagging from either side of the machine.
Is the Airtac SAID63 Double Rod Cylinder SAID63X500S the Right Cylinder?
Choose this double-rod SAID over a single-rod SAI when your application demands equal push/pull forces, twin-station actuation, or rear-rod position sensing. If you need less force, the 50mm bore offers 825N both ways at 0.5MPa; stepping up to the 80mm bore provides 2268N. Note that a plain SAID does not hold its load when air is exhausted; for position holding without live pressure, consider the SAIL or BSAID clamp-lock variants.
At 500mm stroke, the extended rod length increases the risk of side-load bending on the rod bearing; an external guide is highly recommended to support the load. The mounting accessory set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Specify the PT port, required mounting bracket, and CMSE/DMSE sensors for your ISO 15552 replacement.

- ✓ 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 SAID63X500S FAQ
The double-rod design means the effective area is identical both ways, providing an equal extend and retract force of 1402N at 0.5MPa, 1962N at 0.7MPa, and 2523N at 0.9MPa.
Yes, the SAID63X500-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses a standard 63mm bore, 500mm stroke, G3/8 PT port, and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
