Zealous Built-In Longboard Skateboard Bearings (Steel and Ceramic)

Type *

Zealous Bearings were not the first built-in bearing, but they probably be credited with bringing them into the mainstream. They designed a high quality bearing with built in spacers/speed rings and dual rubber seals. There isn't much more to ask for. 

Check out the Zealous Ceramics for a lighter, stronger, and smoother roll than metal ball bearings. Ceramic balls are also corrosive resistant. 

Each bearing has a removable and strengthened Nylon Ball Retainer. Green (steel) or White (ceramic) rubber seals keep dirt and debris on the outside of the bearing.

The most special feature about Zealous is that each bearing is lubed with Custom Nanoceramic Grease. This grease, called Archoil is a nanoceramic compound that fills in deformations or asperities in the bearing. These deformations would 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.
