Strengthened Nylon Ball Retainers 
White rubber seals to keep dirt and debris on the outside of the bearing. 
Lubed with Custom Nanoceramic Grease 
-The unique feature of our lubricant is how the nanoceramic compound fills in deformations or asperities in the bearing. These deformations cause friction and heat around them which hardens the nano-ceramic compound to that specific area. This micro coating is 5 times the hardness of the host alloy and has a molecular bond with the host metal, filling in all the asperities and eliminating friction over time. 
-The coefficient of friction is the lowest in the field of Tribology at 0.003% creating a near frictionless surface. Mainly because the nanoceramic compound eliminates all asperities. 
-Corrosion on the inside of the bearing is nearly eliminated. 
Set of 8 bearings.

"Well packaged, received quickly and no problems at all. Price wasn't bad either. Only just fitted the bearings so will have to wait a bit to see how they break in but so far so good"

Déçu !!! ces roulements céramic roulent pas mieux qu'un premier prix de chez Décathlon peut etre faut il les roder x kms, j'ai préféré rincer la graisse de la cage en les trempant dans du nettoyant vitres , résultat ils tournent beaucoup mieux mais pas autant que mes abec9 classic encore des roulements longue durée ( au placard )

"Très bon rapport qualité prix pour ces roulements avec entretoises intégrées, ils roulent aussi bien que les Red Céramic qui sont pourtant 2 fois plus cher, montés sur des roues de 75 mm de diamètre on roule plus vite et beaucoup plus longtemps. A voir s'ils sont facile à entretenir et s'ils durent avec le temps."
