The description of zirconia ceramic parts
In order to prolong the service life and decrease the maintenance cycles of textile machines, technical ceramic wire guides have been widely used in almost all textile machinery because of super wear resistance, high hardness, antistatic, and low friction.
With our 15 years of manufacturing, We have hundreds of standard ceramic eyelets for customers' selection.
