E-painting (also known as 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 e-paint process. Using this solution over competing products with a fully electrically conductive bearing can significantly reduce paint debris.
