About the Airtac SAID200 Double Rod Cylinder SAID200BX65
The AirTAC SAID200X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 65mm stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding exactly 15079 N of thrust and pull force at 0.5 MPa in either direction. This through-rod design is built with SUS304 stainless steel rods (option B) for superior corrosion resistance in harsh environments.
A 65mm stroke is a non-standard made-to-order length for this bore, but it preserves the full ISO 15552 mounting interface. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that the rear protruding rod requires adequate clearance in your machine layout to prevent mechanical interference during operation.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX65 Is Used
Symmetric Force Transfer
Drives heavy workpiece shuttles requiring exactly 15079 N of push and pull force at 0.5 MPa, ensuring consistent cycle times in both directions without speed variation.
Twin-Station Actuation
Uses the rear SUS304 rod end to drive a secondary mechanism or tool simultaneously, keeping two independent processes perfectly synchronized from one pneumatic input.
Anti-Rotation Slides
Leverages the dual-rod geometry to guide heavy loads and prevent torsional twist during short 65mm clamping or positioning strokes in large presses.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX65 the Right Cylinder?
Select this specific 200mm bore, 65mm stroke configuration when an application demands symmetric force and high corrosion resistance. If you need slightly less thrust, stepping down to the 160mm bore yields 9425 N both ways at 0.5 MPa, whereas moving up is impossible as 200mm is the largest standard SAID size. The twin SUS304 rods provide excellent anti-rotation guidance and allow mounting a secondary cam or position flag on the rear rod end, which is impossible with a single-rod SAI.
This model uses PT tapered port threads (G3/8) and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552 for drop-in replacement of other ISO 15552 double-rod cylinders. Because this is a non-standard 65mm stroke, ensure your rear-rod clearance accommodates the protrusion. Remember that a plain SAID does not hold a load when air is lost; for position holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.

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 SAID200 Double Rod Cylinder SAID200BX65 FAQ
The double-rod design provides equal force in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID200X65 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing the standard Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories.
