The Sun Hydraulics W9R (Material Number: W9R) is a motor mount manifold designed for direct mounting applications, specifically interfacing with Danfoss OMT motors. It features a robust construction with a body type optimized for motor mounting, ensuring seamless integration into hydraulic systems. The manifold includes four mounting holes with a diameter of .42 inches (10.7 mm) and a through-hole depth, complemented by counterbores measuring .69 inches (17.5 mm) in diameter and .54 inches in depth. This design supports secure attachment and stability during operation. The W9R model includes one open cavity, identified as T-17A, and is equipped with SAE 16 port sizes to facilitate fluid transfer within the system. This product is crafted from 6061-T651 aluminum, known for its excellent corrosion resistance and strength-to-weight ratio, making it suitable for various hydraulic applications where durability and reliability are paramount. However, it should be noted that manifolds constructed from aluminum are not rated for pressures exceeding 3000 psi (210 bar). The design considerations ensure that the W9R model can effectively manage hydraulic flow while maintaining structural integrity under specified conditions. Ideal for use in systems requiring efficient motor control and protection, the Sun Hydraulics W9R manifold is an essential component in optimizing hydraulic motor performance. Its compatibility with Danfoss OMT motors allows for versatile application across different setups, providing flexibility and ease of installation to meet specific operational needs.

Show FAQ

Why does Sun use 6061 aluminum?	6061-T651 is relatively strong, relatively inexpensive, difficult to machine, readily available in all shapes and sizes and very corrosion resistant. 2024 is stronger and machines beautifully, but is expensive and falls to pieces in a corrosive environment.
Why doesn't Sun anodize their aluminum bodies?	Reasons to anodize: To increase corrosion resistance. Sun uses 6061-T651 aluminum. It is one of the most corrosion resistant aluminum alloys there is. Whether or not anodizing improves the corrosion resistance of 6061 aluminum is debatable. We have yet to have a manifold returned because of corrosion. Appearance (color). The 2 colors that would appeal to Sun would be blue or black. Unfortunately these are the colors that are hardest to do consistently. To provide a hard wear surface. Sun does not make parts-in-body valves. The manifold is just plumbing. We don't need a wear surface. Because everyone else does it. Bad reason. Reasons to not anodize: Cost. It's another process. Logistics. When you make tens of thousands of manifolds a month and you anodize hundreds, it's a problem. Consistency. See above. Stamping. After a body is anodized you cannot do any more stamping without making a mess.Inspection. Have you ever tried to look for burrs in a black anodized body? It's the old blackboard factory at night scenario. Torque. You will experience an increase in breakaway torque when removing items from an anodized manifold. Fatigue life. This is the best reason to not anodize. Fatigue failure is a very complex phenomenon. What it takes to initiate a crack is difficult to predict. What it takes to propagate a crack is readily defined. Anodizing produces a very thin, very hard, and very brittle surface on aluminum. The first time you pressurize an anodized aluminum manifold you have initiated fatigue cracks. Whether or not the stress is enough to propagate the cracks is a matter of pressure and manifold geometry. Anodizing an aluminum manifold grossly reduces the fatigue life by anywhere from 20% to 50%.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Notes:

Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
