R8VV 12.7 x 28.6 x 7.9mm Bearing ABEC5

The machining precision is of the highest level "ABEC-5", the chrome steel balls are grade 5, with maximum hardness (R-64) and polished surface. Their silent movement on the 52100 alloy raceway (chrome, carbon, aluminum) reaches a very high level of precision. Please note that "MAX" type bearings should be preferred for suspension pivots.

This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip, full-contact LLU (grey)  seals facing outwards to withstand daily abuse of use and the elements, and lighter-contact LLB (black)  seals facing inwards to contain the 90% fill with high pressure water proof grease.
