Precision bearings of the Zealous brand especially suitable for the practice of downhill on longboard, streetluge, buttboard, skate ... (not suitable for inline skates).
Because of its 'Built In' construction, no spacers or washers are required. The center track is recessed to the outside to eliminate the washer and to the inside to eliminate the spacer. By eliminating all these parts, we can eliminate clearances and obtain greater accuracy of fit for the smoothest possible turning.
Manufactured in high quality steel with a high degree of polishing on the races and its 7 balls, Nylon retainer and lubricated with special Nanoceramic compound grease make them very fast bearings.
The removable covers make cleaning and re-lubrication quick and easy.
-Ceramic balls are lighter, stiffer, smoother and naturally corrosion resistant. This means we can use a lower viscosity lubricant which makes them fast right out of the tube.
Precision 8mm axle holes
.4045″ built in spacers
.5mm built in speedrings
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.
Sold in sets of 8 bearings.
