Description of alumina ceramic wire roll guide:
Our ceramic wire roll guides are as varied as our pulley, both single or multiple grooves are available, also the dimensions can be customized. These ceramic roller guides are made of 96%, 99% or 99.5% aluminum oxide ceramics, call it alumina, with diamond polished running surfaces.
Alumina is a kind of improved technical ceramics, these ceramic yarn rollers promote the winding efficiency a lot in textile machinery because of its low friction, superb wear resistance, anti-static electricity features.
