Avid RC are proud to announce the release of the Avid 5x12x4 Revolution bearing for the Xray 808 1/8th scale buggy clutch. What makes this bearing unique is that it has a rubber seal on one side while having a metal shield on the other. Rubber seals are great protectors against dirt but they offer a little more friction due to the tighter seal and thats why these bearings only use one. Xray choose a larger bearing for their new buggy to withstand the load and in doing so they actually made this bearing specific for RC, meaning that nothing else in the world uses this size. Typically this means that the bearing will cost more, however Avid are keeping their industry changing price point of just $1.
