The Sun Hydraulics CRK (Material Number: CRK) is a subplate designed with an ISO 05 interface, featuring P to T bottom ports. This product is constructed with a T3A cavity and accommodates SAE 10 port size. The subplate includes one open cavity, making it versatile for various hydraulic applications. The body type is specifically engineered for optimal performance and reliability in hydraulic systems. It is crafted from 6061T651 aluminum, which offers a balance of strength, cost-effectiveness, and corrosion resistance, making it suitable for demanding environments. Despite the benefits of anodizing aluminum for increased corrosion resistance and appearance enhancement, Sun Hydraulics opts not to anodize this component due to considerations such as cost implications, logistical challenges in high-volume production, consistency issues, stamping complications post-anodizing, inspection difficulties, increased breakaway torque during disassembly, and significant reductions in fatigue life due to the brittle surface created by anodizing. This design choice ensures that the manifold remains durable and reliable under pressure without compromising its integrity over time. The CRK subplate's robust construction and thoughtful design make it an excellent choice for integrating into complex hydraulic systems where reliability and performance are paramount.

Show FAQ

How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
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%.
