These PluckyClover 608 Skate Bearings 608 feature 7 ceramic beads for precise, high speed  stability. The outward facing ceramic bead design makes it more convenient for daily cleaning and maintenance than traditional bearings. High precision Si3n4 ceramic balls can bear higher temperatures, and when the bearing is under very fast speed rotation,the balls won’t expand. This can help to ensure a faster speed and longer life of the bearing.
