组合导线轮（瓷轮）：用于漆包线或丝线适量导向，其中部瓷圈由精密陶瓷制作，凹槽超精抛光达ra0．2，瓷圈配高速轴承，两侧的挡板可防止绕线时漆包线跳出槽外，同时使绕线时的张力保持稳定一致，也有直接由全陶瓷与高速轴承组合的叫陶瓷瓷轮。适用于各类绕线机及纺织机械中的过线过丝部件。assembledwirerollel(ceramicroller):applicableforreasonableguidingofvariousenameledwiresandsilks.themiddleceramiccoilismadeofpreciseceramicandmatchedwithhigh-speedbearing.thegrooveispolishedtora0.2.bafflesinbothsidescanpreventtheenameledwiretojumpoutofthegrooveduringwindingandthewindingtensioncanbemaintainedinastablemanner.or,wholeceramiciscombinedwithhigh-speedbearing,whichiscalledceramicrollerandisapplicableforwireorrollingofvariouswindingmachinesandtextilemachinery.)
