Electrophoretic deposition (also known as e-painting or e-coating) is a process of evenly and quickly coating structures in paint by using electric charge to bond the paint to the structure. For all parts of a given structure to be coated, they need to be electrically conductive.
Figure 1: Cross-section through the unique NORGLIDE® laminate that will perform consistently throughout the lifetime of the part due to the thick PTFE layer. In this case the insulating PTFE layer is used to eliminate undesirable paint-bridges. An example of an electrically conducting notch can be seen on the LR bearing.
This results in a bearing that allows current-flow to all parts that need to be coated, whilst offering insulation at the mating component interface, eliminating paint bridges that would otherwise cause defects in the electrophoretic painting process. Using this solution over competing products with a fully electrically conductive bearing can significantly reduce paint debris.
