-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.
Sold in sets of 8 bearings.

Zealous stands out with a high level of quality and affordable pricing. They are the only built-in spacer bearings which I can recommend at the moment while being 100% sure that they will not disappoint you. Some individuals might disagree but most people who have tried Zealous bearings will nod their head when I say “Zealous bearings are definitely one of the best built-in spacer bearings on the market right now”.
