Description of alumina ceramic bobbin:
Our ceramic bobbin 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.
