6808 Deep Groove Ball Bearing Material

6808 ball-bearing uses the polymer material. The polymer material is pressed into the free space of the bearing. This leaves a very small gap between the polymer and the rolling elements or the raceways, which allows the bearing parts to circulate freely. The polymer material has a sponge-like structure with millions of microscopic pores, which retain the lubricating oil due to the surface tension. In operation, the polymer matrix releases the lubricating oil into the small gap and thus ensures effective lubrication.

Note: When pressing in ball bearings, always make sure that the bearing is always pressed in via the outer ring, which is also the seat of the bearing.

Example hub: The hub body bearings are pressed in there via the outer ring. The bearing may therefore only be pressed in via the outer ring. Never over the inner ring.
