About the Airtac SAID200 Double Rod Cylinder SAID200BX600
The AirTAC SAID200X600 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. Because a piston rod extends from both end covers, the effective annulus area is identical on the extend and retract strokes, yielding an equal both-way force of 15079 N at 0.5 MPa. This through-rod architecture allows you to drive a primary workpiece on one end while mounting a position flag or secondary cam on the rear rod. Equipped with a SUS304 stainless steel rod, this variant offers superior corrosion resistance for harsh environments. It features adjustable air cushioning at both ends (50 mm cushion length) to decelerate the payload smoothly.
Operating at pressures from 0.15 to 1.0 MPa, this cylinder uses a G3/4 port and maintains a speed range of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches. It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX600 Is Used
Heavy-Duty Transfer
Drives large industrial transfer arms with equal push and pull force, ensuring stable momentum for heavy metal payloads.
Symmetric Actuation
Powers dual-station mechanisms where the rear rod simultaneously operates a secondary valve or limit flag.
Anti-Rotation Guidance
Utilizes the twin through-rods to keep heavy guided slides perfectly aligned and prevent torsional twisting.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX600 the Right Cylinder?
Selecting the SAID200X600 is ideal when your application requires massive bidirectional force and high resistance to torsional load. If you need slightly less force, stepping down to the 160 mm bore yields 9425 N both ways at 0.5 MPa, but the 200 mm bore is necessary for payloads requiring the maximum 15079 N output. The double-rod design is chosen over a single-rod SAI when precise anti-rotation guidance or dual-side actuation is required. For this 600 mm stroke, the long unsupported rod span means side-load and rod-bearing bending risks are significant; an external guide rail must be used to prevent premature wear. Mounting options are limited to the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR accessories found on single-rod variants. Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, consider the SAIL lock or BSAID clamp-lock series. Ensure you order the PT tapered port configuration and specify the -S magnet if you require sensor integration.

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 SAID200BX600 FAQ
Because the double-rod design creates equal annulus areas on both sides of the piston, the output force is identical in both directions: 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X600 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, featuring a PT G3/4 port and an extruded aluminum profile barrel.
