Ceramic eyelets are used for enameled wire guidance, and the working surface roughness can reach Ra0.2. Due to the high hardness and smooth surface of ceramics, the friction coefficient is very small. For parts with low requirements, it can be used as a guide, and the enameled wire slides on its surface without damage
Ceramic eyelets are divided into rough, polished, single-sided fine polished, and double-sided fine polished according to the requirements of use.
