Low cost    

At first sight it may seem that the FC concept will result in a cost increase, given the high number of parts. However, quite the opposite is true. The cups can be manufactured using low cost metal forming techniques like deep drawing. Many of the other parts of the design can be manufactured with the same or similar non-swarf technologies like forging and fine blanking. Their precision and surface quality is excellent for hydraulic parts. In the automotive world these production methods are already widely used, including for hydraulic components like hydraulic valve lash adjusters.
The FC concept also offers cost advantages because of reduced tolerances. The introduction of the floating cups breaks the chain of tolerances, which is hindering the possibilities for cost reduction of conventional axial machines. An expensive barrel is replaced by low cost parts. Compared with current bent axis pumps and motors, the costs of the bearings are strongly reduced. Finally regarding costs for use of multiple units, through drive of two or more units (piggy backing) can be realised easily.
