Our 6902 Ceramic Ball Bearing, also known as a 61902 size Ceramic Ball Bearing, is ABEC 7 and engineered for super high performance perfect for wheel hubs or anywhere a high performance 6902 bearing is needed. These size 6902 high performance ball bearings are from World Champion ACER Racing’s Ceramic Nitride Pro Series collection. They include diamond polished Grade 5 Silicon Nitride balls, which are the hardest ceramic balls on the planet (even harder than the white ceramics), dual removable no contact seals so they are completely serviceable, a high speed low noise low friction nylon cage, and 100% synthetic American lubrication. Lighter, faster: the ACER Racing way since 1989. Inner diameter is 15mm, outer diameter is 28mm and width is 7mm.

We also offer a non-ceramic version of this 6902 bearing from our ACERSport collection at a reduced price HERE
